If the potential is constant around a point, what will be the electric field intensity at that point?

Define electric field intensity at a point.

Define electric field intensity at a point.

Define electric field and electric field intensity at a point.

The intensity of electric field at a point is

From the concept of potential gradient find the expression of the electric field intensity at a point in the field of an isolated point charge.

In the diagram shown electric field intensity will be zero at a point.

If the intensity at a point in an electric field is zero, will the electric potential be also zero at that point? If the electric potential be zero at a point, will the intensity be also zero at the point?
