If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.

Vedclass · Answer

(A) In a conductor,the net electric field inside the material is zero because the free electrons redistribute themselves to cancel any external electric field. Due to this redistribution,the net charge inside the volume of the conductor is zero,and all excess charges reside on the outer surface of the conductor. According to Gauss's Law,if there is no charge enclosed within a cavity inside a conductor,the electric field inside that cavity must also be zero. Thus,the reason correctly explains why the electric field is zero in the cavity,as the charges reside only on the surface,leaving the interior (including the cavity) field-free.

Assertion : In a cavity within a conductor,the electric field is zero.
Reason : Charges in a conductor reside only at its surface.
