## What is the electric potential at point on the equatorial line of an electric dipole?

Electric potential at any point in the equatorial plane of dipole is **zero**.

## How electric potential for a dipole can be calculated?

We called it “magnitude of the electric dipole moment vector”, and we denoted this with P. In terms of electric dipole moment vector magnitude, then the potential can be expressed as **P times cosine of θ over 4π ε0 r2.**

## How do you find the potential energy of a dipole?

**P.E=−pEcosθ=−p⋅E**. This is negative when θ is acute and positive when θ is obtuse.

## What is the potential at center of dipole?

Potential at the center of an electric dipole is **zero**.

## What is the equatorial line of electric dipole?

**A line perpendicular to the axial line and passing through the midpoint of electric dipole** is called its equatorial line. Consider a point P on the equatorial line of an electric dipole (situated in a vacuum) at a distance r from the midpoint O of the electric dipole of length 2a as shown in figure.

## What is the electrostatic potential due to an electric dipole at an equipotential point?

Positive sign for 0 = 0° and negative sign for @ = Tt. At any point on the equatorial plane, e = cos = cos = 0. V=0 i.e., electrostatic potential at any point on the equatorial plane of dipole **is zero**. An equipotential surface is that surface at every point of which electric potential is the same.
