Consider the concentric metal sphere and spherical shells that are shown in the figure below. The innermost is a solid sphere that has a radius R1. A spherical shell surrounds the sphere and has an inner radius R2 and an outer radius R3. The sphere and the shell are both surrounded by a second spherical shell that has an inner radius R4 and an outer radius R5. None of the three objects initially have a net charge. Then, a negative charge -Q0 is placed on the inner sphere and a positive charge +Q0 is placed on the outermost shell.
(a) After the charges have reached equilibrium, what will be the direction of the electric field between the inner sphere and the middle shell?
(b) What will be the charge on the inner surface of the middle shell? (Use the following as necessary: Q0.)
(c) What will be the charge on the outer surface of the middle shell? (Use the following as necessary: Q0.)
(d) What will be the charge on the inner surface of the outermost shell? (Use the following as necessary: Q0.)
(e) What will be the charge on the outer surface of the outermost shell? (Use the following as necessary: Q0.)
