A particle of mass m attached to one end of a thin light inextensible string moves with speed v in a circle of radius ro in free space Calculate the work required to reduce the radius from ro to r by pulling the other end of the string through a smooth tube that is perpendicular to the plane of the circle Express the result in terms of m Vo To and r
