A) 1
B) \[\frac{{{R}_{1}}}{{{R}_{2}}}\]
C) \[\frac{{{R}_{2}}}{{{R}_{1}}}\]
D) \[{{\left( \frac{{{R}_{1}}}{{{R}_{2}}} \right)}^{2}}\]
Correct Answer: B
Solution :
Let particle A be situated on the inner part and B on the outer part of the ring. As the ring is moving with uniform angular speed, so their angular accelerations are zero, therefore both the particles will experience centrifugal force only. \[\frac{{{F}_{1}}}{{{F}_{2}}}=\frac{m{{\omega }^{2}}{{R}_{1}}}{m{{\omega }^{2}}{{R}_{2}}}=\frac{{{R}_{1}}}{{{R}_{2}}}\] Hence, the correction option is (b).You need to login to perform this action.
