Physics - Electrostatics Question with Solution | TestHub

An electric dipole is kept on the axis of a uniformly charged ring at distance$\raisebox{1ex}{$R$}\!\left/ \!\raisebox{-1ex}{$\sqrt{2}$}\right.$from the centre of the ring. The direction of the dipole moment is along the axis. The dipole moment is$P$, the charge of the ring is$Q$and the radius of the ring is$R$. The force on the dipole is nearly
