Why is the electric potential at a point on the equatorial line of an electric dipole is zero?

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.

Where does the electric potential due to electric dipole become zero?

At the midpoint of the charges of the electric dipole, the electric field due to the charges is non zero, but the electric potential 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 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.

In which orientation a dipole placed in uniform electric field is in a stable b unstable equilibrium?

A dipole placed in a uniform electric filed is in Stable equilibrium when the electric field is directed along the direction of the dipole i.e., when is parallel to. Unstable equilibrium when the electric filed is directed at an angle of 180 degrees with the direction of the dipole, i.e., when is anti-parallel to.

At what angle potential energy is zero?

When the angle between the dipole moment and electric field is zero then the potential energy of electric dipole is minimum.

What are the points at which the electric potential of a dipole has a minimum value?

The minimum potential energy of the dipole does not mean the potential energy to be zero. The potential energy of the dipole is minimum when the dipole is parallel to the external electric field.

When the point P lies on the equatorial line of the dipole 90 and COS 0 then VP?

Answer: If the point P lies on the equatorial line of the dipole, then θ = 90°. Hence, V = 0.
