JEE MAIN - Physics (2022 - 29th July Morning Shift - No. 11)
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 given below.
Both Statement I and Statement II are correct
Both Statement I and Statement II are incorrect
Statement I is correct but Statement II is incorrect
Statement I is incorrect but Statement II is correct
Paaiškinimas
Since $${\overrightarrow E _{net}} = \overrightarrow 0 $$ in the bulk of a conductor
$$\Rightarrow$$ Potential would be constant.
$$\Rightarrow$$ Statement I is correct
Since a conductor's surface is equipotential, $$\overrightarrow E $$ just outside is perpendicular to the surface.
