The electric potential at a point on the axis of an electric dipole depends on the distance $X$ of t

Question

The electric potential at a point on the axis of an electric dipole depends on the distance $X$ of the point from the centre of the dipole and is proportional to\

Professor PC Thomas Classes · Answer

1. Potential due to a dipole is $\mathrm{V} \propto \frac{1}{\mathrm{X}^{2}}$ \ 2. Potential due to point charge is $\mathrm{V} \propto \frac{1}{\mathrm{X}}$ \ 3. Field due to a dipole is $\mathrm{E} \propto \frac{1}{\mathrm{x}^{3}}$ \ 4. Field due to point charge is $\mathrm{E} \propto \frac{1}{\mathrm{X}^{2}}$
