MCQ
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.

  • 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 and statement $II$ is correct

Answer

Correct option: A.
Both statement $I$ and statement $II$ are correct
a
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.
