हिन्दीConsider the following statements regarding electrostatic shielding: (A) A closed conductor shields its internal cavity from all external electric fields. (B) The electric field inside an empty cavity within a conductor depends strictly on the curvature of the outer surface. (C) Even if a conductor carries excess charge, the electric field inside its empty cavity remains zero. (D) In electrostatic shielding, lines of force pass straight through the cavity without any deflection. How many of the above statements are correct?
Correct answer · Option 2
Only two
Explanation
Only two statements (A and C) are correct. (B) is false (E=0 regardless of shape/curvature) and (D) is false (field lines do not enter the cavity at all).
