Question

Let V and E denote the gravitational potential and gravitational field at a point. It is possible to have
A. `V=` and `E=0`
B. `V=0` and `E!=0`
C. `V!=` and `E=0`
D. `V!=0` and `E!=0`

Answer 1

Correct Answer - A::C::D
From relation `|E|=(dV)/(dr)`
When `V=0, E=0`, when `V=` constant , `E=0`, when `V=!=, E=!=`
So, option a, c and d are correct.
