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

A system consits fo a thin charged wire ring of radius R and a very long uniformly charged thread oriented along the axis of the ring, with one of its ends coinciding with the centre of the ring. The total charge of the ring, with one of the ring so equal to q . The charge of the thread (per unit length) is equal to lambda . Find the interaction froce between the ring and the thread.

A system consists of a thin ring of radius R and a very long uniform wire oriented along axis of the ring with one of its ends coinciding with the centre of the ring. If mass of ring be M and mass of wire be lambda per unit length, calculate interaction force between the ring and the wire.

A very long uniformly charged wire oriented along the axis of a circular ring of radius R rests on its centre with one of the ends (as shown in figure). The linear charge density on the wire is lambda . Evalute the flux of the vector vecE across the circle area.

A thin circular wire of radius r has a charge Q. If a point charge q is placed at the centre of the ring, then find the increase in tension in the wire.
