Question

electric potential at any point of dipole derivation​

Answer 1

Therefore, the electric potential due to an electric dipole at a given point is equal to KPcosθr2−a2cos2θ. ... (i) When the given point is on the axial line of the dipole (i.e. θ=0). Substitute θ=0 in equation (iv). Therefore, V=KPcos0r2−a2cos20
