Question

two circular wheels of radii r and 4r undergo uniform motion circular motion each of them completes 20 revolution in 10 sec the angular speeds are in the ratio
​

Answer 1

Answer:

1:1

Explanation:

As they are completing same revolutions in equal time interval their angular speed will be equal. And it will not depend upon their radii.

So the ratio will be 1:1

Answer 2

Answer:

angular speeds have the same ratio

Explanation:

It is given that both the circular wheels complete the same number of rotational motion which is 20 revolutions and in the same time, hence there angular speeds will be the same.

Angular speed = Angular distance / time

If we apply the formula to both we shall get the same value for both hence their angular speeds have the same ratio
