Homework Statement Find the average potential over a spherical surface of radius R due to a point charge q located inside. Homework Equations V(ave)=V(centre) + Q(enc)/(4*pi*epsi*R) Where V(centre) is the potential at the centre due to all the external charges, and Q(enc) is the total...

Does that mean that if the shell had a hole through it and we wanted to move the charge from the inner radius to the outer radius, the work would be zero?

If a charge is placed inside a spherical conducting shell, is the total electric field inside it zero? I am thinking that if the charge is positive, then the conducting shell will have an equal amount of negative charge on its inner surface, therefore the E field should be zero inside, right?
