Q. If the magnitude of intensity of electric field at a distance $x$ on axial line and at a distance $y$ on equatorial line on a given dipole are equal, then $x:y$ is

A) $1:1$
B) $1:\sqrt{2}$
C) $1:2$
D) $\sqrt[3]{2}:1$
Explanation

(d) $E_{axial} = E_{equatorial} \Rightarrow k.\frac{2p}{x^{3}} = \frac{k.p}{y^{3}} \Rightarrow \frac{x}{y} = \frac{2^{1/3}}{1} = \sqrt[3]{2}:1$
