A stretchable conducting ring is in the shape of a circle. It is kept in a uniform magnetic field (B) that is perpendicular to the plane of the ring. The ring is pulled out uniformly from all sides so as to increase its radius at a constant rate dr/dt = V while maintaining its circular shape. Calculate the rate of work done by the external agent against the magnetic force when the radius of the ring is r0. Resistance of the ring remains constant at R.
