Elec. Potential due to a hollow metallic sphere at any point inside the sphere(may be center) when the charges are on the surface , is equal to the potential at the surface if the total charge is concentrated at the center.
Elec. Potential due to a hollow metallic sphere having radius' R' at a distance 'r' from the centre of the sphere is
(I) for r
(ii) for r=R,V = q/4π€R
(iii) for r>R, V = q/ 4π€r
