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

A${m_1}:{m_2}$

B${r_1}:{r_2}$

C$1:1$

D${m_1}{r_1}:{m_2}{r_2}$

(AIPMT-1999)

Solution

(c)As time periods are equal therefore ratio of angular speeds will be same. $\omega = \frac{{2\pi }}{T}$
