An electrostatic system consists of two earthed concentric spherical shells of very small thickness and of radii "a" and "2a" respectively. The region a ≤ r ≤ 2a bears a charge distribution: $\gamma = \gamma_o (\frac{a}{r})$

\gamma_o = constant

1. Determine a value for \gamma_o if the total charge is Q.

2. Show that the potential is:

3. Sketch the directed electric field configuration of the system.

$\psi_r = \frac{Q}{4\pi a}[\frac{3}{2}-\frac{1}{2} \frac{a}{r} - \frac{a}{r}]$
