E is zero as the field lines cant penetrate the metallic shell. this is known as electrostatic shielding.the potential v on the other hand is non zero in the shell.
this is because potential is defined as a scalar quantity and it is the work done in bringing a charge from infinity to that point.
the potential everywhere inside the shell is the same as there is no electric field to exert force which in turn would have done work and hence would have changed the potential.
also E=dV/dr which implies that if E=0 then V is a constant quantity.
