Unfortunately this very notion makes it more confusing and hard to understand. The whole notion of attraction and repulsion of charged particles is attributed to the exchange of virtual photons. Originally this was a question that came under the realm of quantum field theory. Unlike the previous case, both of you now experience a force that brings you close to each other (A boomerang might be a better tool). Your friend can throw the frisbee and curve it in such a way that you catch it from your front. On the other hand, visualizing attraction is a bit more tricky but, this time think of the same situation where you and your friend are facing away each other and both of you are skilled frisbee throwers. Clearly you can connect this to the repulsion of two particles by exchanging photons. Instead of standing on the ground if you conduct the experiment standing on two small boats on water, the effect will be more vivid. You would experience the same effect when you throw the ball and this repeated throwing and catching push you further apart. Every time you catch the ball thrown by your friend you receive a small force pushing you backward because of the conservation of linear momentum. ![]() ![]() Think of you and your friend are standing facing each other, a certain distance apart, throwing a football back and forth. Having said that though, let me try to explain it from a nontechnical point of view which is generally presented most of the time. This is truly hard to visualize from a classical/semiclassical point of view. Could you please tell me how Quantum field Theory describes the attraction and repulsion of two charge particles via exchanging photon?
