Q. 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.

JEE MainJEE Main 2022Electrostatic Potential and Capacitance

Solution:

(Properties of conductor)
Statement - I, true as body of conductor acts as equipotential surface.
Statement - 2 True, as conductor is equipotential. Tangential component of electric field should be zero. Therefore electric field should be perpendicular to surface
