Question

The circular disk spins at a constant number of revolutions per second. Moving from point A to point B, the

angular velocity increases.
angular velocity decreases.
linear velocity increases.
linear velocity decreases.

Answer 1

C edge

Explanation:

Answer 2

The disk spins at a constant number of revolutions per second. This means, the angular velocity is constant.

We know that,

Linear velocity = r x Angular Velocity
where r is the radius.

So, for a given angular velocity, larger value of r will have larger Linear velocity. Since the value of r at point B is more than at point A, the value of Linear velocity will be more at point B.

So, the correct answer is option C
