Question

the electric potential due to a small electric dipole at a large distance r from the centre of dipole is proportional to

Answer 1

The electric potential due to a small electric dipole at a large distance r from the centre of dipole is proportional to $\bold{\frac{1}{r^2}}$

Actually, electric potential due to dipole is $\bold{\frac{KPcos{\theta}}{r^2}}$ where K is kappa constant ,
P is magnitude of the dipole ,
θ is the Ange between axis of dipole and observation point.
r is the distance between centre of dipole to observation point.
