two cars having masses m1 and m2 move in circles of radii r1 and r2 resp, if they complete the circles in equal time, ration of their angular speeds omega1/omega2 is:

a) m1/m2

b)r1/r2

c)1

the ans is 1 ,

Pls explain.

both cars cover angular dispalcement of 360 degrees .

and it is given that t₁ = t₂

thus angular velocity for both is equal.

acceleration and force on each car differs.
