A system consisting of one positively charged particle and onenegatively charged particle is altered by an outside force so thatits potential energy increases by 6.25 mJ. There is no changein kinetic energy between the initial and final states of the system. (a) What is the work done by the outside force? (b) What is the work done by the electric force? (c) Are the particles closer together or farther apart after the system's rearrangement?
