Physics · Electrostatic Potential
हिन्दीAn uncharged conductor containing an empty cavity is placed in an external electrostatic field. The potential at any point inside the cavity:
Correct answer · Option 3
Is constant and equal to the potential of the conductor
Explanation
Since E = 0 inside the cavity and across the conductor body, dV/dr = 0, meaning V is constant everywhere and equal to V_conductor.
