Q. If $E_{a x}$ and $E_{e q}$ represents electric field at a point on the axial and equatorial line of a dipole. If points are at a distance $r$ from the centre of the dipole, for $r >> a$

$E_{a x} = E_{e q}$

$E_{a x} = - E_{e q}$

$E_{a x} = - 2 E_{e q}$

$E_{e q} = 2 E_{a x}$

The field at axial point of a dipole is double of equatorial point of a dipole.
$∴ E_{axial} = - 2 E_{equatorial}$

Q. If Eax​ and Eeq​ represents electric field at a point on the axial and equatorial line of a dipole. If points are at a distance r from the centre of the dipole, for r>>a

Eax​=Eeq​

Eax​=−Eeq​

Eax​=−2Eeq​

Eeq​=2Eax​
