two point charges exert an attractive force of 5.0 N on each other. How much force would they exert on each other if the distance between them were: a) ten times as great b) one-tenth as great c) how would your answers to a and b be altered if at all if the forces the charges exert on each other were repulsive rather than attractive? (please include all steps/formulas used)
