How the electric field due to an electric dipole is different from that of a point charge?
Asked by Topperlearning User | 16th Apr, 2015, 01:25: PM
1. The electric field produced by a point charge at a point from the charge is given as
that is the field will fall off as inverse square of the distance.
whereas electric field due to dipole is given by
(at a point on the axis of the dipole)
(at a point on the equatorial plane)
which means that electric field falls off not as 1/y2 but as 1/y3, so the electric field due to the dipole falls off much faster than the field due to a point charge.
2. Also, the magnitude and the direction of the dipole field depend not only on the distance y but also on the angle between the position vector and the dipole moment.
