Two racing cars of masses m1 and m2 are moving in circles of radii

1.	Two racing cars of masses m1 and m2 are moving in circles of radii r1 and r2 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) m1 : m2(b) r1 : r2(c) 1 : 1(d) m1r1 : m2 r2
Answer» Correct Option (c) 1 : 1 Explanation: As time periods are equal therefore ratio of angular speeds will be same ω = 2π/T
