To whirl a stone tied to a cord one has to move the free end of the chord on a circular path pulling the stone on a larger circular path In this way a stone of mass m is whirled on a horizontal circular path of radius R with the help of a light inextensible cord of length by moving the free end on a circular path of radius r with a uniform speed v as shown in the figure At sufficient great speed tensile force in cord becomes so large that the effect of gravity can be neglected but at this speed air resistance becomes considerable The force of air resistance is expressed as NR n R given 1 nr F mv Path of the hand Find N R Path c the stor
