Two stones of masses m and 2m are whirled in horizontal circles, the heavier one in a radius 
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 
is
Text Solution
Verified by ExpertsThe correct answer is:
C
Let 
be tangential speed of heavier stone. Then, centripetal force experienced by lighter stone is
and that of heavier stone is
But
