Electric field and potential at a point

[Amith2006]

1)Say whether true or false:
If electric potential at a point is zero, then the electric field at that point is zero.

I think the answer is false because the electric potential due to a dipole at a point on its perpendicular bisector is zero but the field is not zero. Is it right?

Yes. There are tons of examples - take a perfect conductor for instance. Inside the conductor there is no electric charge and no field. But the potential is not zero at all. So False.

Thanks for the guidance.

take a perfect conductor for instance. Inside the conductor there is no electric charge and no field. But the potential is not zero at all.

That is not an appropriate example. The question asks if the field is zero when the potential is zero, not the other way.

But 'False' is still the correct answer to the question. :)
