Two racing cars of masses m(1) and m(2) ...

Two racing cars of masses `m_(1)` and `m_(2)` are moving in circles of radii `r_(1)` and `r_(2)` respectively. Their speeds are such that each makes a complete circle in the same duration of time t. The ratio of the angular speed of the first to the second car is

A

`m_(1) : m_(2)`

B

`r_(1) : r_(2)`

C

`1:1`

D

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

Text Solution

Verified by Experts

The correct Answer is:
C
Since, `omega = (2pi)/7`. As time periods are equal therefore ratio of angular speeds will be same.
