Two stones of masses m and 2 m are whirled in horizontal circles, the heavier one in a radius r/2 and the lighter one in radius r. The tangential speed of lighter stone is n times that of the value of heavier stone when they experience same centripetal forces. The value of n is :
1
2
3
4

Solution:

m(nω)²×r = 2m(ω)² ×(r/2)

so, n =1
