A metallic sphere with charge -Q is placed inside a hollow conducting sphere with radius R carrying charge +Q. The potential at a point outside the hollow sphere
1
Depends on the position of the metallic sphere
2
Is solely decided by the charge on the outer sphere
3
Is always zero whatever may be position of the inner sphere
4
Is zero only when both spheres are concentric
