The electric field due to a dipole
therefore falls off, at large distance, faster than like 1/r 2 (the dependence
on r of the field due to a single charge q) 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
