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
Both the cars make a complete circle in the same time T, which means that angular speeds of both the cars are same
`because omega = V/r =(2pi r)/(Tr) = (2pi)/T`
