1E = - dV/dr
if E is not = 0 V can never be equal to 0.
So above statement is impossible.
Let V and E denote Gravitational Potential and Gravitational field at a point.
Is it possible to have V=0 but E≠0 ?

23aveek i didnt get ur logic , if a curve has no point of extremum, why cant it be zero? [eg: f(x)=x has no point of extremum but it is zero at some x ]
btw wat if i choose an arbitrary point as zero potential which has a nonzero electric field ??????
suppose i choose the potential at the earth's surface to be zero. Clearly electric field isnt zero.
so it is possible
1@Qwerty
But if we proceed with the equation i.e.
E = -dv/dr
Here if we put V=0 then E must be 0 as derivative of 0 is 0.
I guess you meant 'gravitational field'.
1i agree with qwerty potential at a point depends on the reference we choose
