Solution
Correct Answer:
Same as that on the surface
- Inside a Charged Conductor: For a hollow metal sphere (or any conductor) in electrostatic equilibrium, the electric field (E) is zero everywhere inside.
- Relation between E and V: E=−drdV. If E=0, then V must be constant.
- Boundary Condition: The potential must be continuous across the surface.
- Conclusion: Since the potential is constant inside and equal to the surface value, the potential at the center is the same as that on the surface.
This easy difficulty physics question is from the chapter electrostatics, covering the topic of electric potential. It appeared in the 2025 exam.
