The law of the energy of interaction in electrostatics is very simple; we have, in fact, already discussed it. Suppose we have two charges q1q1 and q2q2 separated by the distance r12r12. There is some energy in the system, because a certain amount of work was required to bring the charges together. We have already calculated the work done in bringing two charges together from a large distance.
