MHT CET Physics question

In a gravitational field, at a point where the gravitational potential is zero

(A)The gravitational field is necessarily zero
(B)The gravitational field is not necessarily zeroCorrect
(C)Nothing can be said definitely about the gravitational field
(D)None of these

Answer: (B)

Solution

The field is the negative gradient of the potential, so a zero potential does not imply zero field (the zero of potential is only a reference choice, so
