Answer 1

:

Let an electric dipole consist of two equal and opposite point charges –q at A and +q at B ,separated by a small distance AB =2a ,with centre at O. The dipole moment, p=q×2a. We will calculate potential at any point P, where ... i.e electric potential due to an electric dipole is zero at every point on the equatorial line of the ..
