Quiz 4 A solid spherical conductor of radius a is concentric with a hollow spherical conducting shell of inner radius 1) and outer radius 6, as shown. The central sphere carries a charge Q, and the shell carries a charge q. Assume that the electric potential goes to
‘ zero infinitely far from the conductors. (3 pt.) Find the electric potential for r > c, where r
is the distance from the centers of the conductors. v.5 Smm’k’lfi‘” CW4 (62%):
