This is usually done by invoking the uncertainty principle. For example, with an electron and positron, you can say that a virtual photon is emitted from the electron, thus carrying away a well defined momentum and allowing the electron to recoil towards the positron.I have studied feyman's charge- photon interactions which successfully explains repulsions between like charges, but can someone explain me attraction on basis of feyman's diagram,using charge-photon interactions?
