A solid spherical conductor is given a charge. The electrostatic potential of the conductor is

1. constant throughout the conductor
2. largest at the centre
3. largest on the surface
4. largest somewhere between the centre and the surface

Electric potential is constant (equal to kq/R ,where k = 1/4πε₀)
within or on the surface of conductor.
