Two racing 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 each makes a complete circle in the same time $t$. The ratio of the angular speeds of the first to the second car is

  • A

    $1 : 1$

  • B

    $m_1 : m_2$

  • C

    $r_1 : r_2$

  • D

    $m_1m_2 : r_1r_2$
