Charge on a hollow sphere

(Fig. 22.25c). The surface of the ball becomes part of the cavity surface. The sit-uation is now the same as Fig. 22.23b; if Gauss's law is correct, the net charge on the cavity surface must be zero. Thus the ball must lose all its charge. Finally, we pull the ball out; we find that it has indeed lost all its charge.
