Two racing cars having masses `m_(1)` and `_(2)` move in concentric circles of radi`r_(1)` and `r_(2)` respectively . If their angular speeds are same , then the ration of their linear speeds 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

b

Explanation

We know that ,v `=romega`
Thus, `(v_(1))/(v_(2))=(r_(1)omega_(1))/(r_(2)omega_(2))" "becauseomega_(1)=omega_(2)" "therefore(v_(1))/(v_(2))=(r_(1))/(r_(2))`
