Statement-1: A device used to measure is located a some distance from a fixed point charge. In this situation, the device measures as the magnitude of electric field intensity. Now an uncharged conducting sphere with a very small hole is lowered by an insulating thread so that it surrounds the point charge. Now, the reading of the device becomes zero.
Statement-2: Electrostatic shielding is the phenomenon in which inside of hollow conductor is shielded for outside electric field.
Statement-2: Electrostatic shielding is the phenomenon in which inside of hollow conductor is shielded for outside electric field.
View answer and explanation
Correct option: C
Statement-1 is true, Statement-2 is false
Statement-1 is true because the electric field inside a conductor is zero. Statement-2 is false because electrostatic shielding is a true phenomenon.
