A system consisting of two positive particles is altered by anoutside force so that its potential energy decreases by52.3 J. There is no change in kinetic energy between theinitial and final states of the system. (a) What is the work doneby the outside force? (b) What is the work done by the electricforce? (c) Are the particles closer together or farther apart afterthe system's rearrangement?
