Question

obtain an expression for electirc field due to an electric dipole at a point on the line passing through the centre of diople and perpendicular to the dipole axis

Answer 1

Answer:

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.
