Question

If the electric potential on the axis of an electric dipole at a distance r from it is v then the potential at a point on its equitorial libe

Answer 1

Answer  ⇒ Thus, at any point of equatorial line, electric potential is always zero.

Explanation ⇒  Electric potential at any general point in case of dipole is given by the relation,

V = kpCosθ/(r² - a²Cos²θ),

where r is the distance of the point from centre of dipole.

Now, At Axial,

θ = 0

Thus, V = kp/(r² - a²)

But At Equatorial,

θ = 90

Thus, V = 0

Thus, at any point of equatorial line, electric potential is always zero.

Hope it helps.

Answer 2

Explanation ⇒ Electric potential at any general point in case of dipole is given by the relation, V = kpCosθ/(r² - a²Cos²θ), where r is the distance of the point from centre of dipole. Thus, at any point of equatorial line, electric potential is always zero. ❤️
