In Exercise 39, write expressions for the electric field magnitude
In exercise A solid conducting sphere is surrounded by a thick, spherical conducting shell. Assume that a total charge +Q is placed at the center of the sphere and released.
(a) In the interior of the solid sphere,
(b) Between the sphere and the shell,
(c) Inside the shell, and
(d) Outside the shell. Your answer should be in terms of Q, r (the distance from the center of the sphere), and k.
