Two identical conducting spheres each carry a net electric charge; Ball A carries –3μC and Ball B carries +7μC. The spheres are briefly brought near each other, and then allowed to touch (so that charge can flow from one sphere to the other), and finally separated. The electric forces between Ball A and Ball B are: a.) Attractive, both before and after they are touched together. b.) Attractive before they are touched together, and repulsive after. c.) Repulsive before they are touched together, and attractive after. d.) Repulsive, both before and after they are touched together
