Assertion : In a cavity within a conductor, the electric field is zero. Reason : Charges in a conductor reside only at its surface.
Options:
Answer:
A
Solution:
Both the assertion and reason are true and the reason is the correct explanation. It is because the charges are only at the surface of a conductor; the charge enclosed in the Gaussian surface in the cavity is zero. The field is therefore zero.
