why do opposite charges attract and like charges repel

Isn't both the electric field and magnetic field consist of virtual photons? How virtual photons give rise to electric and/or magnetic field? How should I ask my new chair not to hire someone? The protons and electrons have electric fields around them and it helps them attract the opposite charge but the electric field around similar charges repels each other. Novel about a man who moves between timelines. For the Electro-magnetic force (Coulomb) between like charges (electrons) the exchange particle is the Photon. The last is called deductive reasoning. in electron-positron annihilation with photon production (talking about low energies only) there's electromagnetic interaction (is it?) The "how" is given by the corresponding mathematical theory of quantum electrodynamics. QED mathematically describes all phenomena involving electrically charged particles interacting by means of exchange of photons and represents the quantum counterpart of classical electromagnetism giving a complete account of matter and light interaction. As a result, two negative charges repel one another, while a positive charge pulls a negative charge toward it.

Now consider $$\mathscr{L}=F_{\mu\nu}F^{\mu\nu}+j^\mu A_\mu$$ I thought once more and deleted my downvote. When an atom loses the negatively charged electrons it becomes positively charged and when new electrons enter an atom it becomes negatively charged. it's just for the magnitude of the force, if you want the proper direction then use the vector form of coulomb's law. This demo may be used by charging the electroscopes via induction rather than conduction. About the original question, which was not "why particles interact" but "why do like charges repel", it can not find the calculation in Dyson's. (a) The glass rod is attracted to the silk because their charges are opposite. That is, a positively charged object will exert a repulsive force upon a second positively charged object. Virtual particle, Starting the Prompt Design Site: A New Home in our Stack Exchange Neighborhood, Physics.SE remains a site by humans, for humans. Objects with similar charges are drawn to one another. $$Action = \int -mc^2 d\tau -\frac{q}{c} A_\mu dx^\mu$$ We also share information about your use of our site with our social media, advertising and analytics partners. Here's the an, Posted 4 months ago. When the charge on one body Q is significantly higher than the charge on the other Q and the two bodies are sufficiently close to one another, the force of attraction between Q and the induced charge on the other body Q is greater than the force of repulsion between Q and q. Electrostatic force is the interaction of two electric charges. In contrast to oppositely charged particles, those with the same charge repel one another. (Objects with the same charges repel one another.) law of electric charges. Coulomb's law, or Coulomb's inverse-square law, is a law of physics that describes force interacting between static electrically charged particles. Direct link to 's post how do I calculate force , Posted 3 years ago. By suspending pieces of tape from a straw, you can build an electroscopea device that detects electrical charge. To log in and use all the features of Khan Academy, please enable JavaScript in your browser. Multiplying by $\frac{dt}{dt}$ I am confused with my teacher's explanation and hoping for help here. Can you pack these pentacubes to form a rectangular block with at least one odd side length other the side whose length must be a multiple of 5. This is necessary because there should be a smooth continuity in the predictions of the solutions of the models in phase spaces where both views could be used to calculate and predict charged particle behaviors. They will repel each other if their charges are the same. The attraction or repulsion forces acting between two charges are always of the same magnitude and act in opposite directions. Move the electroscopes close together and the braids on each electroscope will repel each other (Figure 1). 1 2 3 Attraction and repulsion Opposite (unlike) charges attract one another. h A negatively charged object has gained electrons. In this way, the two electrons repel each other by shedding momentum via the photon and giving it to the other electron, which gains momentum and flies off.

Principle of superposition for charges/induced charges, Investigating the 1d Equation: Charges & Field Disparity, Help with FLP argument of non-uniformly distributed surface charges. When a positive charge is brought closer to a negative charge, excess number photons from the positive charge get transferred to the negative charge, so that the number of photons in both the charges are balanced. Direct link to alyanna (aqua217)'s post *If there are two charges, Posted 3 months ago. The source of electrical charge is the attraction between protons and electrons in the atom, and the repulsion of each for its own kind. Spaced paragraphs vs indented paragraphs in academic textbooks, Beep command with letters for notes (IBM AT + DOS circa 1984). As a result of the EUs General Data Protection Regulation (GDPR). For electromagnetic interactions are needed minimum two different types of particles. electrical conductor. Direct link to Bruce Xu's post is r measured in cm? a . Direct link to Noor Naveed's post in "CGS" system [centi;gr, Posted 3 years ago. Does the debt snowball outperform avalanche if you put the freed cash flow towards debt? The braids of the electroscope will diverge from the base. By convention, objects likely to lose electrons are called negative, and objects likely to gain electrons are called positive. What causes like to repel like and opposites to attract at the smallest level. Can anybody tell me if it appears in Sakurai's or perhaps in Aitchinson. He described electricity as a fluid that flows from objects with excess electrical fluid (positive) to objects with a deficit of electrical fluid (negative). Answer: ADEH A and D are true; they are the simple statement of our essential charge interactions, best remembered by the jingle: "opposites attract, likes repel." B and C are false for these same reasons; they violate the basic statement of charge interactions. Direct link to Sal's post Hello Parv. Furthermore we could follow the model of electric and magnetic field lines. Why are particles the mass they are, we don't know either. A negative charge wants to give away its electrons to become neutral therefore it attracts positive charge towards it. Could somebody expand on this? electric force. The braids on each electroscope will remain diverged until brought into contact with other charges. To be slightly optimistic, there are lots of people on this site who can give a hopefully much, much better answer than I. But if its all virtual photons, how do we get the difference between a magnetic and electric field? It only takes a minute to sign up. On the other hand, particles with like charges, repel. The forces of attraction push each other apart like two magnets with the same pole (e. g. equally North). I could say it's to keep conservation laws from bring broken, or that charges exchange photons, but if I understand your question correctly, that is not the explanation you want. Letting $\vec{B}=\vec{0}$, $\vec{E}=\frac{\vec{F}}{q}$ Why is there inconsistency about integral numbers of protons in NMR in the Clayden: Organic Chemistry 2nd ed.? $$\frac{\vec{F}}{q}=\frac{kq}{r^2}\hat{r}$$ Opposite charges, such as a positive charge and a negative charge, attract each other. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. The models differ from maps because they not only fit existing data/measurements but are also predictive of new results of experiments and observations. Like charges repel each other (positive to positive or negative to negative). This research by Whydo is supported by our readers. Is it usual and/or healthy for Ph.D. students to do part-time jobs outside academia? Why is the gravitational force always attractive? The attraction created by a collection of protons in the nucleus is greater than the repelling force that the electrons exert against one another. New framing occasionally makes loud popping sound when walking upstairs. The force is inversely proportional to the square of the distance between two charges. A property of matter that determines the force on the object when placed in an electromagnetic field. What is the what is the opposite of repel? Ball (2012), Nature News: Like attracts like, Starting the Prompt Design Site: A New Home in our Stack Exchange Neighborhood, Physics.SE remains a site by humans, for humans. I am confused with my teacher's explanation and hoping for help here. Due to their negative charge, electrons repel one another. When two particles with dissimilar charges are drawn together, the lines of force converge. etc etc, @sofky yes, "whys" can be answered by a mathematical theoretical model ,by"how" using the models/equations the trajectories etc can be explained, but these raise further "whys" which are nested, until they hit a basic postulate, which, same as the mathematical axioms, have to be accepted for the theory to hang together and describe the measurements.

Connect and share knowledge within a single location that is structured and easy to search. $$F^\mu=eF^\mu_\nu u^\nu$$ This means that charge can get redistributed non-uniformly on their surfaces. In between the two charges, there is an area of attraction or repulsion. rev2023.6.29.43520. For physicist in universitary education this seems sometimes to be strange. Protons mutually repel each other because charges of the same sign repel. No tracking or performance measurement cookies were served with this page. How can I handle a daughter who says she doesn't want to stay with me more than one day? If you have any sources explaining clearly, I would also appreciate that. Though I haven't done any QED maths, the theoretical explanation is sufficient enough for a layman to get a gist of how things happen. Magnets are the basis for generating electricty and coul. The reason they did not attract each other is because the electrons and nucleus of an atom have opposite chargesthe electrons are negatively charged and the nucleus is positively charged. Why do atoms repel when closer but attract when farther apart? How to describe a scene that a small creature chop a large creature's head off? How do charged particles interact with each other? Does the debt snowball outperform avalanche if you put the freed cash flow towards debt? When two charged objects are brought close to one another, depending on the type of charge each one carries, they either attract or repel one another. How can I differentiate between Jupiter and Venus in the sky? The best answers are voted up and rise to the top, Not the answer you're looking for? Opposite charges attract each other (negative to positive).
