Two bodies of masses m and 3 ~m are rotating in horizontal circles of radius r and r 3 respectively. The tangential speed of body of mass m is n times that of the value of heavier body. while the centripetal force is same for both. The value of n is

Options

  1. A3
  2. B9
  3. C1
  4. D6

Correct answer

A. 3

Step-by-step solution

Centripetal force is same on both, therefore: aligned & m(n v)^2 r = 3 m v^2 ( r 3 ) & n^2=9 & n=3 aligned
