Text Solution

Verified by Experts
The correct answer is:
A
Explanation: When dealing with an isolated conducting solid sphere, it is important to consider the properties of conductors in electrostatic equilibrium.
  • Properties of Conductors: In electrostatic equilibrium, the electric field inside a conductor is zero. This implies that all excess charge resides on the surface of the conductor.
  • Uniform Distribution: For a symmetrically shaped conductor (like a sphere), when an excess charge is placed, it will spread out evenly across the surface to minimize the repulsive forces and maintain electrostatic equilibrium.
  • Conclusion: Therefore, the charge on an isolated conducting solid sphere must be distributed uniformly on its surface.

Therefore, the correct option is A.
