A non conducting rod `AB` of length `sqrt(3)R`, uniformly distributed charge of linear charge density `lambda` and a non-conducting ring of uniformly distributed charge `Q`, are placed as shown in the figure. Point `A` is the centre of ring and line `AB` is the axis of the ring, perpendicular to plane of ring. The electrostatic interaction energy between ring and rod is
