Two particle move in concentio cireles of radii `r_(1)` and `r_(2)` such that they maintain a straight line through the centre. The ratio of their angular veocities is:

A

`(r_(1))/(r_(2))`

B

`(r_(2))/(r_(1))`

C

one

D

`(1)/(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
The particles A,B and the centre of the circle always lie on a straight line . i.e., A and B have equal angular displacements is equal intervals of time .
` i.e., omega_(1) = omega_(2) "or" (omega_(1))/(omega_(2))=1`
