due to
a dipole, when the point is taken on
the axis of
the dipole.​

Answer 1

Explanation:

A dipole of dipole moment p ​=pi^ is kept at the center of circle of radius r as shown in the figure. The radius of the circle is very large in comparison to the distance between the two charges of the dipole. A & B are two points on the axis and C & D are two points on the equatorial line of the dipole.
