A) 1
B) \[\left( \frac{{{R}_{1}}}{{{R}_{2}}} \right)\]
C) \[\frac{{{R}_{2}}}{{{R}_{1}}}\]
D) \[{{\left( \frac{{{R}_{1}}}{{{R}_{2}}} \right)}^{2}}\]
Correct Answer: B
Solution :
Let panicle \[A\] is situated on the inner part and \[B\] on the outer part of the ring. As the ring is moving with uniform angular speed therefore, both particles will feel centrifugal force. \[\therefore \] \[\frac{{{F}_{1}}}{{{F}_{2}}}=\frac{{{F}_{A}}}{{{F}_{B}}}=\frac{m{{\omega }^{2}}{{R}_{1}}}{m{{\omega }^{2}}{{R}_{2}}}\] \[\Rightarrow \] \[\frac{{{F}_{1}}}{{{F}_{2}}}=\frac{{{R}_{1}}}{{{R}_{2}}}\]You need to login to perform this action.
