Two concentric charged metal spherical shells are held fixed in space. All other charges are very far away. The smaller shell (call it shell A) has an inner diameter of 5 [cm], an outer diameter of 10 [cm], and a total charge of +10 [nC]. The larger shell (call is shell B) has an inner diameter of 25 [cm], an outer diameter of 30 [cm], and a total charge of +10 [nC]. Find the electric field (Both magnitude and direction) at the following distances from the center of the shells. (Let r = 0 at the center of the concentric shells.) HINT: Gauss' Law.

  1. a) r=2[cm]

  2. b) r=4[cm]

  3. c) r=10[cm]

  4. d) r=14[cm]

  5. e) r=20[cm]

    Please Justify Answers and Show All work. 3. Two concentric spherical metal shells have radii a and 2a as shown in the figure on the right. The outer shell has a charge Q, but the inner shell is grounded. This means that the inner shell is at zero potential. While its potential is zero, the inner shell is not electrically neutral. The outer shell induces a charge lin on the inner shell. (The charges are taken from ground). Answer the...
