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.

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
