Your question: What is the electric potential due to an electric dipole on equatorial plane?

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 we can explain potential at any point on the equatorial line of dipole is zero find the minimum and maximum value of magnitude of the potential of a dipole?

The potential at a point due to an electric dipole will be maximum and minimum when the angles between the axis of the dipole and the line joining the point to the dipole are respectively. V=pcosθr2. If θ=0∘ then Va=max. If θ=180∘ then Ve=min.

What is the work done in moving a test charge q through a distance of 1 cm along the equatorial axis?

What is the work done in moving a test charge q through a distance of 1 cm along the equatorial axis of an electric dipole ? ∴W=q×V=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.
