A charge Q is placed on a hollow metal ball. We saw in Chapter 21 that the charge is all on the surface of the ball because metal is a conductor. How does the charge distribute itself on the ball?
(a) Half on the inside surface and half on the outside surface.
(b) Part on each surface in inverse proportion to the two radii.
(c) Part on each surface but with a more complicated dependence on the radii than in answer (b).
(d) All on the inside surface.
(e) All on the outside surface.
