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

What is the angle between maximum value of potential gradient and equipotential surface?
  1. 0
  2. π4
  3. π2
  4. π

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.
