For the Electro-magnetic force (Coulomb) between like charges (electrons) the exchange particle is the Photon. What if the like attracts and opposite repel? Two electrons in the vicinity of each other exchange a photon with each other (back and forth) that results in the mutual repulsion. I have read in a number of places how substances with opposite charges attract each other: The excess electrons in the one substance repels the electrons in the other substance so that they move away from the surface, leaving the protons closer to the surface which are then attracted to the excess electrons in the one surface.
