What is the angle between maximum value of potential gradient and equipotential surface?

Options

  1. A0
  2. Bπ 4
  3. Cπ 2
  4. Dπ

Correct answer

C. π 2

Step-by-step solution

The angle between Electric field and an equipotential surface is always 90 . This is because,when the potential becomes constant,the negative potential gradient also becomes zero,hence necessitating the need for Electric field to be always normal with surface.
