Q. The electric field at a point on the equatorial plane at a distance r from the centre of a dipole having dipole moment $P$ is given by ( $r >>$ separation of two charges forming the dipole, $\in_{0}$ -permittivity of free space)

$E = \frac{P}{4 π \in _{0} r ^{3}}$

$E = \frac{2 P}{4 π \in _{0} r ^{3}}$

$E = \frac{P}{4 π \in _{0} r ^{2}}$

$E = - \frac{P}{4 π \in _{0} r ^{3}}$

$E = \frac{K P}{r ^{3}}$
$E = - \frac{P}{4 π \in _{0} r ^{3}}$

Q. The electric field at a point on the equatorial plane at a distance r from the centre of a dipole having dipole moment P is given by (r>> separation of two charges forming the dipole, ∈0​-permittivity of free space)

E=4π∈0​r3P​

E=4π∈0​r32P​

E=4π∈0​r2P​

E=−4π∈0​r3P​
