The Angular Momentum of a Rotating Cylinder

APPHMC-NZN4U1

A solid cylinder of mass, $m$, and radius, $r$, when rotating at an angular velocity, $\omega$ has an angular momentum $L$.

Which of the following would double the angular momentum of the cylinder?

A

Doubling the mass of the cylinder while halving its angular velocity

B

Doubling the angular velocity of the cylinder while halving its mass

C

Doubling the radius while halving the mass of the cylinder

D

Quadrupling the mass while halving the radius of the cylinder

E

Quadrupling the angular velocity while halving the radius of the cylinder
