(a) On the cross section above right
(b) In the spaces below, rank the electric potentials of points a, b, c, d, and e from highest to lowest (1 = highest potential). If two points are at the same potential, give them the same number.
(c) The shell is replaced by another cylindrical shell that has the same dimensions but is non-conducting and carries a uniform volume charge of +
. The infinite line charge, still of charge density +
, is located at the center of the shell as shown below.
Using Gauss' Law, calculate the magnitude of the electric field as a function of distance r from the center of the shell for each of the following regions. Express your answers in terms of the given quantities and fundamental constants.
