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...
