... 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 qw on the cavity wall, so q + qw = 0 and qw = –q = –3.0 × 10–6C. (b) The net charge Q of the conductor is the sum of the char ...
