$A$ system of two charges separated by a certain distance apart stores electrical potential energy. If the distance between them is increased,the potential energy of the system,

$A$ short electric dipole has a dipole moment of $16 \times 10^{-9} \, Cm$. The electric potential due to the dipole at a point at a distance of $0.6 \, m$ from the centre of the dipole,situated on a line making an angle of $60^{\circ}$ with the dipole axis is $.........V$. (Given: $\frac{1}{4 \pi \epsilon_{0}} = 9 \times 10^{9} \, Nm^{2}/C^{2}$)

Write an equation of electric potential at a point due to an electric dipole.

When one electron is moved towards another electron,the electric potential energy of the system:

When the distance between two point charges is increased,the electrostatic potential energy of the system:

The electric potential at a point on the axis of an electric dipole depends on the distance $r$ of the point from the dipole as
