Two racing cars of masses \[{{m}_{1}}\] and \[{{m}_{2}}\] are moving in a circles of radii \[{{r}_{1}}\] and \[{{r}_{2}}\] respectively. Their speeds are such that each makes a complete round of circle in the same internal of time. The ratio of their angular speeds are :

A)  \[{{m}_{1}}{{m}_{2}}:{{r}_{1}}{{r}_{2}}\]                              

B)  1:1

C)  \[{{r}_{1}}:{{r}_{2}}\]                                    

D)  \[{{m}_{2}}:{{m}_{1}}\]
