Show that the intensity of electric field at a point on broadside position of an electric dipole is given by:
$E = \left(\frac{1}{4\pi\epsilon_{0}}\right)\frac{p}{(r^{2}+l^{2})^{3/2}}$
where the terms have their usual meaning.
Given: An electric dipole of two point charges $-q$ and $+q$ separated by distance $2l$
To show: $E = \left(\frac{1}{4\pi\epsilon_{0}}\right)\frac{p}{(r^{2}+l^{2})^{3/2}}$
