Vedclass · Answer

(A) The given system consists of two equal and opposite point charges separated by a small distance $L$,which forms an electric dipole.For an electric dipole,the electric field intensity $E$ at a large distance $R$ $(R \gg L)$ from the center of the dipole is given by the general formula:$E = \frac{1}{4\pi\epsilon_0} \frac{p}{R^3} \sqrt{1 + 3 \cos^2 	heta}$where $p$ is the dipole moment and $	heta$ is the angle between the position vector and the dipole axis.Since $p = qL$ is constant,we can observe that $E \propto \frac{1}{R^3}$.Therefore,the magnitude of the electric field intensity varies as $1/R^3$.

Two point charges $-q$ and $+q$ are placed at a distance of $L$,as shown in the figure. The magnitude of electric field intensity at a distance $R$ $(R \gg L)$ varies as:
