Question

Two racing cars of masses and are moving in circles of radii and respectively the ratio of the angular speed of the first to the second car is

Answer 1

Answer:

Hence, the ratio of angular speed of the first car to that of second is 1:1.

Answer 2

Correct Question:

Two racing cars of masses m₁ and m₂ are moving in circles of radii r₁ and r₂ respectively. Find the ratio of the angular speeds of the first to the second car.

Step-by-step explanation:

Let each makes a complete circle in time t.

We know that,

♦ Angular speed, ω = 2π/t

• Angular speed of first racing car, ω₁ = 2π/t

• Angular speed of second racing car, ω₂ = 2π/t

Finally,

The ratio of the angular speeds of the first to the second car = Angular speed of first racing car/Angular speed of second racing car

• ω₁/ω₂ = 2π/t/2π/t
• ω₁/ω₂ = 1/1

Therefore,

The ratio of the angular speeds of the first to the second car = 1:1
