Vedclass · Answer

(C) $1$. Let the charge on inner shell $A$ be $+Q$. Due to induction,a charge of $-Q$ is induced on the inner surface of shell $B$.$2$. Since shell $B$ is earthed,its potential is zero. The potential at $B$ is due to the charge on $A$ and the charge on $B$ itself. Let the charge on the outer surface of $B$ be $q'$. The potential at $B$ is $V_B = kQ/r_B + kq'/r_B = 0$,which implies $q' = -Q$. However,since the shell is earthed,the charge on the outer surface becomes zero,and the total charge on $B$ is $-Q$.$3$. Electric field inside $A$ $(r $4$. Electric field between $A$ and $B$ $(r_A $5$. Electric field outside $B$ $(r > r_B)$: Since the shell $B$ is earthed,the potential is zero,and the charge on the outer surface is zero. Thus,$E = 0$.$6$. Comparing with options: Option $C$ is correct as the electric field between $A$ and $B$ is non-zero.
