Question

Obtain the mathematical expression in of electric field intensity on the axial line of dipole

.​

Answer 1

Answer:

We have been asked to derive an expression for electric field intensity due to an electric dipole at a point on its axial line. Now, let AB be an electric dipole of two-point charges -q and + q separated by small distance 2d. ... Here, (r – d) is the distance of point P from charge +q.
