Transcribed Image Text:22.45 • Concentric Spherical Shells. A small conducting
spherical shell with inner radius a and outer radius b is concen-
tric with a larger conducting spherical shell with inner radius c
and outer radius d (Fig. P22.45). The inner shell has total charge
+2q, and the outer shell has charge +4q.
