Expert Answer
The axial line of a dipole is the line passing through the positive and negative charges of the electric dipole.
Consider a system of charges (-q and +q) separated by a distance 2a. Let 'P' be any point on an axis where the field intensity is to be determined.
Electric field at P (EB) due to +q
Electric field at P due to -q (EA)
Net field at P is given by
As a special case :
