20. A rigid ring is made to roll along the ceiling of a room, where a horizontal uniform and static magnetic field of induction B exists perpendicular to the plane of the ring. Velocity of the centre of the ring is constant and its modulus is v. A charge particle P of mass m is fixed on the ring. What should the charge q on the particle and radius r of the ring be so that there is no force of interaction between the ring and the particle?
