Consider three plastic balls (a, b, and c), each carrying a uniformly distributed charge equal to either +q, -q or zero, and an uncharged copper ball (d). a positive test charge (t) experiences the forces shown in the figure when brought very near to the individual balls. the test charge t is strongly attracted to a, strongly repelled from b, weakly attracted to c, and strongly attracted to d.
assume throughout this problem that the balls are brought very close together. what is the nature of the force between balls a and c?
(a) strongly attractive
(b) strongly repulsive
(c) weakly attractive
(d) neither attractive nor repulsive
