86 × 106  N C–1 along PA
The resultant electric field at P due to the two charges at A and B is
=  2 7 × 105  N C–1  along BP In this example, the ratio OP/OB is quite large (= 60) Thus, we can
expect to get approximately the same result as above by directly using
the formula for electric field at a far-away point on the axis of a dipole
