A mass m moves in a circle plane with velocity v in a circule of radius R 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 R R slowly and finally m moves in a circle of radius The final value of kinetic energy is 1 mv 2 1 3 mv 2 mv 4 2mv 2
