Two large, thin, charged plastic circular plates each of radius R are placed a short distance s apart; s is much smaller than the dimensions of a plate. The right-hand plate has a positive charge of +Q evenly distributed over its inner surface (Q is a positive number). The left-hand plate has a negative charge of -2Q evenly distributed over its inner surface. A very thin plastic spherical shell of radius r is placed midway between the plates (and shown in cross section). It has a uniformly distributed positive charge of +q. You can ignore the contributions to the electric field due to the polarization of the thin plastic shell and the thin plastic plates. Charged plate I 3r B 3r 1²-1 A + +q + 1. Ia, IIc 2. Ic, IIc 3.
