Angle between `vecE` and equipotential surface is always

A

`0^(@)` to `180^(@) `

B

`0^(@)` to `90^(@) `

C

`0^(@)` always

D

`90^(@)` always

Text Solution

Verified by Experts

The correct Answer is:
D
When potential becomes constant, the negative potential gradient also becomes zero. This causes `vecE` to be normal to the surface.
