If electrostatic field at a point is zero, must the electrostatic potential be also zero at that point?

Following are two statements about the relationship between the electric field an electric potential. If the electric field at a certain point is zero, the nthe electric potential at the same point is also zero.

If the electric field intensity E at a point is zero, will be the electric potential be necessarily zero at the point?

Is electrostatic potential a scalar or a vector quantity?

SI unit of electrostatic potential enegy is………….

What is the unit and dimenstions of electrostatic potential?
