Question

Can electric potential be zero at a point in a vacuum, the electric field at that point is not zero. Give example.

Answer 1

Yes, Electric Potential is zero at a particular point, it does not necessarily mean that the electric Field is also zero at that point. It can be understood with the Case of Electric Dipole.

*electrostatic potential can be zero at a point where electric field is not zero. Consider two charges +Q and -Q separated by a distance d.

*There can exist electric potential at a point where the electric field is zero. Example:Inside the hallow spherical charged conductor, electric field is zero but potential is not zero.

Points which maybe helpful for you to understand much better :

****Electric field is a Force and potential or voltage is the energy required to overcome this force or the energy required to move a particle from one position to other . When electrical field is zero, the energy required to overcome it will also be zero.****

****The zero of electric potential (voltage) is set for convenience, but there is usually some physical or geometric logic to the choice of the zero point. For a single point charge or localized collection of charges, it is logical to set the zero point at infinity.****
