Physics20233 marksDerivation
Show that intensity of electric field at a point in 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 having charges $-q$ and $+q$ separated by distance $2l$

To show: $E = \left(\frac{1}{4\pi\epsilon_0}\right) \frac{p}{(r^2 + l^2)^{3/2}}$
