How does the angular velocity change as a result of doubling the radius?

A

The angular velocity is doubled when the radius is doubled.

B

The angular velocity is halved when the radius is doubled.

C

The angular velocity is quadrupled when the radius is doubled.

D

The angular velocity is quartered when the radius is doubled.
