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...

Flux and nonconducting shells. A charged particle is
suspended at the center of two concentric spherical shells that are
very thin and made of nonconducting material. Figure (a)
shows a cross section. Figure (b) gives the net fluxΦ through a Gaussian sphere centered on the particle, as a
function of the radius r of the sphere. The scale of the
vertical axis is set by Φs = 4.5 ×
105 N·m2/C. (a) What is the
