MCQ
Two particles having mass $M$ and $m$ are moving in a circular path having radius $R$ and $r$. If their time period are same then the ratio of angular velocity will be
  • ✓
    $1$
  • B
    $\frac{ r }{ R }$
  • C
    $\frac{R}{r}$
  • D
    $\sqrt{\frac{R}{r}}$
✓

Answer

Correct option: A.
$1$
a
As $\omega=\frac{2 \pi}{T}$

$\omega \propto \frac{1}{T}$

$\frac{\omega_1}{\omega_2}=\frac{T_2}{T_1}$

$T_1=T_2$

$\frac{\omega_1}{\omega_2}=1$
