A net charge of +Q is transferred to a spherical conducting shell of
inner radius a and outer radius b. A point charge - q is placed in
the center of the shell. What is the charge density on the outside
of the conducting shell?
(a) o = -q/4 n b²
b
(b) o = -Q/4 n b²
a
(c) o = (Q – q)/4 r b²
(d) o = (Q + q)/4 n b²
(e) o = (q - Q)/4 n b²
