Particle moving in a circle (angular momentum)

[preluderacer]

Homework Statement

A particle is moving in a circle. If the radius of the circle is doubled and the angular speed remains the same, then the angular momentum of the particle about the center of the circle will also be doubled.

The Attempt at a Solution

Im thinking it's false because the equation mr^2(angular speed). I am not quite sure though if this was the equation to use though.

You are correct, the angular momentum is L=m r w = m r^2 w.
