Question

A permanent dipole creates a net electric field, though it bears no net charge.Explain?​

Answer 1

A permanent dipole creates a net electrostatic field although it does not bear any charge because of the following reasons :

• A Dipole consists of equal and opposite charges placed closed to one another.

• This small distance between the charges lead to net electrostatic field intensity at axial and equatorial positions.

• The electrostatic field intensity at the axial position is double as compared to the field intensity at equatorial position.

At axial position :

$\boxed{E = \dfrac{2kp}{ {r}^{3} } }$

At equatorial position:

$\boxed{E = \dfrac{kp}{ {r}^{3} } }$

k is Coulomb's Constant , p is dipole moment.
