The electric field due to a short electric dipole at a large distance $(r)$ from center of dipole on the equatorial plane varies with distance as :

Options:

Answer:

C

Solution:

An electric dipole is a system of two charges of equal and opposite magnitude placed at a short distance.
The dipole moment is, $p = 2 q l$ .
The electric field due to the dipole is,
$E = \frac{2 k p}{r^{3}}$
Clearly, the electric field varies as $\frac{1}{r^{3}}$ .
