A system consists of a thin charged wire ring of radius r and a vety long uniformly charged wire oriented along the axis of the ring, with one of its ends coinciding with the center of the ring. The total charge on the ring is q. and he linear charge denisity on the straight wire is `lambda`, The interaction force between the ring and the wire is
