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] \[\frac{{{v}_{1}}}{{{v}_{2}}}=\frac{{{r}_{1}}}{{{r}_{2}}}=\frac{R}{r}\]You need to login to perform this action.
