Electric Field Intensity on the axial and equatorial line of an electric dipole.
What is an Axial Line?
The axial line is the line that unites the centers of positive and negative charges that form an electric dipole. Consider an electric dipole consisting of +q and -q charges separated by a distance. Consider a point D at a distance ‘r’ from the center O of the dipole on the axial line of the dipole.
