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