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 any value between one and infinite None of these

the gravitational field is necessarily zero

Gravitational field : \(E_g = - \frac{dV_g}{dr}\) Thus, if \(V_g = 0 \Rightarrow E_g = 0\)
