Question 186 of 311

Given below are two statements.
Statement I : Electric potential is constant within and at the surface of each conductor.

Statement II : Electric field just outside a charged conductor is perpendicular to the surface of the conductor at every point.

In the light of the above statements, choose the most appropriate answer from the options give below.

Show answer and solution

Answer: (A) Both statement I and statement II are correct

Statement - I: True as body of conductor acts as equipotential surface.
Statement II: True, as conductor is equipotential. Tangential component of electric field should be zero. Therefore, electric field should be perpendicular to surface.
