A solid metal ball of radius 1.3 cm is located near a hollow plastic ball of radius 2.1 cm bearing a uniformly distributed charge of -4 nC on its outer surface. The distance between the centers of the balls is 10 cm.
Assume the +x axis runs to the right, the +y axis runs up and the +z axis is out.
(a) What is the electric field at the center of the metal ball due only to the charges on the plastic ball?
(b) What is the net electric field at the center of the metal ball?
(c) What is the electric field at the center of the metal ball due only to the charges on the surface of the metal ball?
