Two particles of mass M and m are moving in a circle of radii R and r. If their time-periods are same, what will be the ratio of their linear velocities?
-
- MR : mr
- M : m
- R : r
- 1 : 1
Correct Option: C
Linear velocity v = rω
v1 = ωr1, v2 = ωr2
[ω is same in both cases because time period is same]
| = | = | |||||
| v2 | r2 | r |
