Show that the intensity of electric field at a point in end on position i.e., axial position of an electric dipole is given by:
$E = (\frac{1}{4\pi\epsilon_{0}})\frac{2pr}{(r^{2}-l^{2})^{2}}$
where the terms have their usual meaning.
Given: Electric dipole consisting of charges $-q$ and $+q$ separated by distance $2l$
To show: $E = (\frac{1}{4\pi\epsilon_{0}})\frac{2pr}{(r^{2}-l^{2})^{2}}$
