The ratio of the electric field of an electric dipole on its axis and on the perpendicular bisector

Question

The ratio of the electric field of an electric dipole on its axis and on the perpendicular bisector of the dipole is

Professor PC Thomas Classes · Answer

Field along the axial line $E_1 = \frac{2kp}{r^3}$, and field along the equatorial line $E_2 = \frac{kp}{r^3}$. The ratio $\frac{E_1}{E_2} = 2:1$.
