Chapter-2|Electrostatic Potential and Capacitance| NCERT 12th Physics:
Electrostatic Potential Due to an Electric Dipole:
Let we consider an electric dipole consisting of charges +q and -q separated by a distance 2a.
Therefore, Dipole Moment P=q×2a
Let O be the centre of dipole, P be any point near the electric dipole inclined at an angle θ.
Now, We have to calculate electric potential at point P.
