Given, that two stones of masses m and 2m are whirled in horizontal circles, the heavier one in a radius r/2 and lighter one in radius r as shown in a figure.



As lighter stone is n times that of the value of heavier stone when they experience same centripetal forces, we get

(Fc)heavier = (Fc)lighter
