(a)
Charge resides on the outer surface of a conducting hollow sphere of radius R. We consider a spherical surface of radius r < R. By Gauss''s theorem,
i.e., electric field inside a hollow sphere is zero.

Field inside a conducting sphere is zero.
Formula of gausses law,
Φ=q/∈0
put q=0, final ans will be zero.
Hope it helps!
