Question:

A point charge Q rests at the center of an uncharged thin spherical conducting shell. (See Fig 16-33). What is the electric field E as a function of r?
(a) For r less than the inner radius of the shell.
(b) Inside the shell, and
(c) Beyond the shell?
(d) Does the shell affect the field due to Q alone? Does the charge Q affect the shell?
