RE-NEET 2026 Physics Electric Field MCQ Question
A point charge Q is placed inside a cavity within a solid isolated conducting sphere. Consider points A, B and C as shown in the figure, where the magnitudes of the electric fields are Eₐ, E_b and E_c respectively. The points B and C are at the same distance from the center of the solid sphere. The correct option is:
Eₐ ≠ 0, E_b = E_c
Eₐ = 0, E_b > E_c
Eₐ ≠ 0, E_b < E_c
Eₐ = 0, E_b = E_c
Correct Answer
Detailed Explanation
Inside a conductor, the electric field is zero. Since B and C are equidistant from the center, their fields must be equal.
