Question: Two 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 they make complete circles in the same time t. The ratio of their centripetal acceleration is :-
$1: 1$
$\mathrm{m}_{1} \mathrm{r}_{1}: \mathrm{m}_{2} \mathrm{r}_{2}$
$\mathrm{m}_{1}: \mathrm{m}_{2}$
$r_{1}: r_{2}$
Correct Option: , 4
Solution:
