Two bodies of masses 8 kg and 4 kg are moving in concentric circular orbits of radii `r_(1) and r_(2) ` respectively . If their time periods are same , the ration of their centripetal accelerations is

A

`r_(1):r_(2)`

B

`2r_(1):r_(2)`

C

`r_(1):2r_(2)`

D

`r_(1): r_(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
`a_(1):a_(2)=r_(1)omega_(1)^(2):r_(2)omega_(2)^(2)=r_(1):r_(2)" " (therefore omega _(1): omega_(2))`
