A small conducting sphere carrying charge $Q$ is surrounded by a spherical uncharged conducting shell. A small charge $+ q$ is placed between the sphere and the shell, then the net charge on the
inner surface of the shell is :

$- Q + q$
$- Q$
$- (Q + q)$
none of the above

For conducting sphere all charges are distributed over the surface- So charge Q will appear on outer surface of the conducting sphere- As the charge inside shell is zero when q is placed between the conducting sphere and shell - -x2212-Q-q- will appear on the inner surface of the shell-

A small conducting sphere carrying charge Q is surrounded by a spherical uncharged conducting shell. A small charge +q is placed between the sphere and the shell, then the net charge on the inner surface of the shell is :−Q+q−Q−(Q+q)none of the above

For conducting sphere all charges are distributed over the surface. So charge Q will appear on outer surface of the conducting sphere. As the charge inside shell is zero when q is placed between the conducting sphere and shell , −(Q+q) will appear on the inner surface of the shell.
