at a radius
A mass, m, moves in a circle on a smooth horizontal plane with velocity, V0, at a radius, R0. The mass is attached to a string which passes through a smooth hole in the plane as shown. The tension in the string is increased gradually and finally m moves in a circle of radius 2/R0. The final value of the kinetic energy is
