NEETPhysicsElectrostatics
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): The electrostatic potential is zero everywhere inside a charged conductor. Reason (R): In a static situation, the electric field inside the conductor is zero and has no tangential component on its surface. In the light of the above statements, choose the most appropriate answer from the options giv
Options
- ABoth (A) and (R) are correct and (R) is the correct explanation of (A)
- BBoth (A) and (R) are correct but (R) is not the correct explanation of (A)
- C(A) is correct but (R) is incorrect
- D(A) is incorrect but (R) is correct
Correct answer
D. (A) is incorrect but (R) is correct
Step-by-step solution
In a static situation, the electric field inside a conductor is zero. Since E = - dV dr , a zero electric field implies that the electrostatic potential V is constant throughout the volume of the conductor, but it is not necessarily zero. It is equal to the potential on the surface. Thus, the Assertion is incorrect. The Reason is correct because in electrostatics, free charges inside the conductor redistribute to make the internal electric field zero. Additionally, the electric field at the surface must be normal t
