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:

Options

A. `(r_(1))/(r_(2))`
B. `(r_(2))/(r_(1))`
C. 1
D. `((r_(1))/(r_(2)))^(2)`

Answer

C

Explanation

`omega_(1) = (Delta theta)/(Delta t) = omega_(2)`
