Question

Two particles of mass M and m are moving in a circle of radii R and r. if their time period are the same, what will be the ratio of their linear velocities?
A. `MR:mr`
B. `M:m`
C. `R:r`
D. `1:1`

Answer 1

Correct Answer - c
Linear velocity `v=romega`
`v_(1)=omegar_(1), v_(2)=omegar_(2)`
[ `omega` is the same in both cases because time periode is the same]
`(v_(1))/(v_(2))=(r_(1))/(r_(2))=R/r`
