Question
Two cars having masses m1 and m2 move in circles of radii r1 and r2 respectively. If they complete the circle in equal time, the ratio of their angular speeds ω1ω2 is _______
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
