Three conducting spherical shells have radii (a, b, and c) such that a lt b lt c (Fig. 3.113). Initially, the inner shell is uncharged, the middle shell has a positive charge Q, and the outer shell has a negative charge -Q . . a. Find the electric potential of the three shells. b. If the inner and outer shells are now connected by a wire that is insulated as it passes through the middle shell, what is the electric potential of each of the three shells ? Also, what is the final charge on each shell ?
