Question

derive the expression for electric potential at a point due to an electric dipole​

Answer 1

Answer:

Therefore, the electric potential due to an electric dipole at a given point is equal to KPcosθr2−a2cos2θ. Special cases: (i) When the given point is on the axial line of the dipole (i.e. θ=0). ... Hence, V=KPcos(π2)r2−a2cos2(π2)=KP(0)r2−a2(0)=0.
