Question
If a positive charge is placed at the center of a hollow conducting sphere, what is the field inside the conductor (between inner and outer surfaces)?
Correct Answer
Option A is the correct answer.
Detailed Explanation
In electrostatic equilibrium, the electric field inside the conducting material itself (the metal) is zero, regardless of charges inside the cavity. The induced charges on the inner surface cancel the field from the central charge within the conductor.
Hint
Conductor interior always has E = 0.
