Question

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.

• A. Both statement I and statement II are correct
• B. Both statement I and statement II are incorrect
• C. Statement I is correct but statement II is incorrect
• D. Statement I is incorrect but statement II is correct

Answer 1

Answer: (A)

Both statement I and statement II are correct

Answer 2

Since, in the bulk of a conductor,
$\vec E_{net}=0$
Therefore, the potential would be constant.
$⇒$ Statement I is correct.
Since a conductor’s surface is equipotential, $\dot E$ just outside is perpendicular to the surface.

So, the correct option is (A): Both statement I and statement II are correct.
