A) \[\frac{{{R}_{2}}}{{{R}_{1}}}\]
B) \[{{\left( \frac{{{R}_{1}}}{{{R}_{2}}} \right)}^{2}}\]
C) 1
D) \[\frac{{{R}_{1}}}{{{R}_{2}}}\]
Correct Answer: D
Solution :
Since,is constant, v would also be constant. So, no net force or torque is acting on ring. The force experienced by any particle is only along radial direction or we can say the centripetal force. The force experienced by inner part,and the force experienced by outer part, \[\therefore \,\,\,\frac{{{F}_{1}}}{{{F}_{2}}}\,=\frac{m{{\omega }^{2}}{{R}_{1}}}{m{{\omega }^{2}}{{R}_{2}}}=\frac{{{R}_{1}}}{{{R}_{2}}}\]You need to login to perform this action.
