These qualitative ideas are
borne out by the explicit calculation as follows:
1 10 1  The field of an electric dipole
The electric field of the pair of charges (–q and q) at any point in space
can be found out from Coulomb’s law and the superposition principle The results are simple for the following two cases: (i) when the point is on
the dipole axis, and (ii) when it is in the equatorial plane of the dipole,
i
