Two cars having masses m1andm2 move in circles of radii r1andr2 respectively. If they complete the circle in equal time, the ratio of their angular speeds ω1ω2 is _______

Options:

A . m1m2

B . r1r2

C . m1r1m2r2

D . 1

Answer: Option D : D ω1=△θ△t If time taken to complete a revolution is t. Then ω1=2πt,ω2=2πt ⇒t=2πω1=2πω2 ⇒ we get ω1=ω2orω1ω2=1
