Question

For an electric dipole (p) i at origin find the value of tan theta at pt A (3,4) here theta is the angle made by resulting electric field and positive x -axis​

Answer 1

Electric dipole moment :

Explanation:

The electric dipole moment is the product of two charges & the product between them.

A dipole is an arrangement of two charges having the same magnitude but opposite direction.

i.e. the electric dipole moment is a vector quantity.

This electric dipole moment is given by

$\displaysyle\mathbf{ \vec{P} = \vec{q}(2\vec{a}})$

where

p =  electric dipole moment

q = charge

a = dipole length

At an angle θ, the electric dipole moment is given by

p = 2 q a cosθ

where θ is the angle between lines of dipole moment.
