Equal charges are given to two spheres of different radii. The potential will

1. Be more on the smaller sphere
2. Be more on the bigger sphere
3. Be equal on both the spheres
4. Depend on the nature of the materials of the spheres

Correct answer: Be more on the smaller sphere

Solution

For an isolated conducting sphere, the potential is \(V = kQ/R\). If both spheres carry equal charge \(Q\), the one with smaller radius \(R\) will have a larger potential. Therefore, the potential is greater on the smaller sphere.
