Q. Figure shows three concentric metallic spherical shells. The outermost shell has charge $q_{2}$, the inner most shell has charge $q_{1}$, and the middle shell is uncharged. The charge appearing on the inner surface of outermost shell isPhysics Question Image

Electric Charges and Fields

Solution:

Suppose a guassian surface passes through conducting shell with radius $\left(r_{3}\right)$
Flux through it well be zero.
So, net charge enclosed must be zero.
$\therefore q_{1}+q'=0 $
$q'=-q_{1}$
