NEET Physics Electric Potential Assertion Reason Question
Assertion (A): Inside a conductor, the electrostatic field is zero. | Reason (R): Free electrons in a conductor move until the internal electric field cancels the external field.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true but R is false.
A is false.
Correct Answer
Detailed Explanation
Inside a conductor, the electrostatic field is zero as the free electrons move to cancel any internal electric field caused by an external field. This is a key property of conductors.
