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 duration of time t.The ratio of the angular speed of the first to the second car is

View answer and explanation

Correct option: C

1:1

Option C (1:1) is correct because angular speed is inversely proportional to the time period, and since the time period is the same, the angular speeds are equal.
