(6.II) Two small identical metal spheres are 3 cm apart and attract each other with a force of 150 N. They are momen- tarily connected by a wire. (a) Find the original charges if they now repel each other with a force of 10 N. (Assume the charge on each sphere is uniformly distributed.) (b) Find the original charges if the magnitude of the repulsive force is 150 N.
