Question

An electric dipole consists of a positive and negative charge of 4uc each placed at a distance of 2mm calculate dipole moment​

Answer 1

Dipole moment is 8 × 10^(-3) Cm.

Given:

• Electric dipole consists of positive & negative charge of 4 uC.
• Separation is 2 mm

To find:

Dipole moment ?

Calculation:

Dipole moment is a vector quantity representing the product of the charge and the separation between the charges.

Let dipole moment be M :

$M = q \times d$

• q is charge and d is separation.

$\implies \: M = (4 \times {10}^{ - 6} ) \times (2 \times {10}^{ - 3} )$

$\implies \: M =8 \times {10}^{ - 9} \: Cm$

So, the dipole moment is 8 × 10^(-3) Cm.
