Vedclass · Answer

(C) When sphere $A$ is given a charge $Q$,it induces a charge $-Q$ on the inner surface of the earthed sphere $B$. Since sphere $B$ is earthed,its potential becomes zero. The electric field inside a conductor is zero,but in the region between the two spheres (where $r_A Using Gauss's Law,the electric field $E$ at a distance $r$ from the center is $E = \frac{1}{4\pi\epsilon_0} \frac{Q}{r^2}$,which is non-zero. Outside the outer sphere $B$,the net charge is $Q + (-Q) = 0$,so the electric field outside $B$ is zero. Thus,the field between $A$ and $B$ is not zero,and the field outside $B$ is zero.

$A$ and $B$ are two concentric spheres. If $A$ is given a charge $Q$ while $B$ is earthed as shown.
