Chapter 22, Problem 48E

(a)

To determine

The electric field in terms of $q$ and the distance $r$ from the common center of the two shells for (i) $r<a$, (ii) $a<r<b$, (iii) $b<r<c$, (iv) $c<r<d$ and(v) $r>d$ and to plot the results in a graph of radial component of $\overrightarrow{E}$ as a function of $r$.

(b)

To determine

the total charge on the (i)inner surface of the small shell,(ii)outer surface of the small shell,(iii)inner surface of the large shell and (iv)outer surface of the large shell.
