MCQ
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
  • A
    $1 : 1$
  • B
    $m_1 r_1 : m_2 r_2$
  • C
    $m_1 : m_2$
  • ✓
    $r_1 : r_2$
✓

Answer

Correct option: D.
$r_1 : r_2$
d
Both have same time period.

$\frac{\omega^{2} r_{1}}{\omega^{2} r_{2}}=\frac{r_{1}}{r_{2}}$
