Two particles A and B are moving in uniform circular motion in concentric circles of radii `r_(A)` and `r_(B)` with speed `u_(A)` and `u_(B)` respectively. Their time period of rotation is the same. The ratio of angular speed of a to that of B will be:

A

`r_(A): r_(B)`

B

`V_(A):V_(B)`

C

`r_(B):r_(A)`

D

`1:1`

Text Solution

Verified by Experts

The correct Answer is:
D

`T_(A)=T_(n)=T`
`omega_(A)=(2 pi)/(T_(A))`
`omega_(B) =(2 pi)/(T_(B))`
`(omega_(A))/(omega_(B))=(T_(B))/(T_(A))=(T)/(T)=1`
