Problem
An ideal electric dipole has dipole moment magnitude 5.0×10−9Cm. Along its axis the electric potential at point P is 2.25×103V.
(i) Determine the distance of point P from the centre of the dipole.
(ii) How far from the centre along the same axis will the potential become one-fourth of the value at P?
