In a gravitational field, at a point where the gravitational potential is zero
In a gravitational field, at a point where the gravitational potential is zero
The gravitational field is necessarily zero
The gravitational field is not necessarily zero
Nothing can be said definitely about the gravitational field
None of these
In a gravitational field, at a point where the gravitational potential is zero
$I = \frac{{ - dV}}{{dx}}$
If $V = 0$ then gravitational field is necessarily zero.
