Question

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 1

Correct Option  (c) 1 : 1

Explanation:

As time periods are equal therefore ratio of angular speeds will be same ω = 2π/T
