    Two particles of mass A/and in are moving in a circle of radii R and r. If their time periods are the same, what will be the ratio of their lineal- velocities?

    A) MR : mr

    B) M: m

    C) R : r

    D)  1 : 1

    Correct Answer: C

    Solution :

    Linear velocity \[v=r\omega \] \[{{v}_{1}}=\omega {{r}_{1}},{{v}_{2}}=\omega {{r}_{2}}\] [\[\omega \] is the same in both cases because time period is the same] \[\frac{{{v}_{1}}}{{{v}_{2}}}=\frac{{{r}_{1}}}{{{r}_{2}}}=\frac{R}{r}\]
