the cavity. Since the electric field is zero everywhere on the surface, the net charge it encloses is zero. The net charge is the sum of the charge q in the cavity and the charge q w on the cavity wall, so q + q w = 0 and q w = –q = –3.0 × 10 –6 C. (b) The net charge Q of the conductor is the sum of the charge on the cavity wall and the
