Detailed Solution

Potential at the surface of a solid metallic sphere may be non-zero, even if net charge on the surface is zero, the potential can be because of some other external charge( As the net charge of surface remains same).

If potential at the center of a solid metallic sphere is non-zero, potential at the surface of the sphere is non-zero, because the centre and the surface will have same potential.( conductor)
