Question

write the relation between electric field on axial and equatorial line when dipole is a very short length?​

Answer 1

Explanation:

The line perpendicular to the axial line and passes through the centre of the electric dipole length is called an equatorial line. Consider an electric dipole AB consisting of +q and -q charges separated by a distance 2l. Let P be the point on the equatorial line at a distance r from the centre O of the dipole.

Answer 2

$E_{axial} = 2$ × $E_{equatorial}$

Explanation:

• $E_{axial}$ = $\frac{k2p}{r^3}$

• $E_{equatorial}$ = $\frac{kp}{r^3}$

• ∴ $E_{axial}$ = 2 × $E_{equatorial}$
