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

Options

A. `m_(1) : m_(2)`
B. `r_(1) : r_(2)`
C. `1:1`
D. `m_(1)r_(1) : m_(2)r_(2)`

Answer

C

Explanation

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