Homework Statement
A single particle of mass m is revolving at steady speed in a circle of radius a about the z axis at a height h above the origin. In this situation the particle has angular velocity w = wz
1 Show that the angular momentum L is not parallel to w
2 If a second particle revolves in the same circle at the opposite end of a diameter, show that the combined angular momentumof the two particles rotating rigiidly is parallel to w.
Homework Equations
The Attempt at a Solution
For the first question, i have found a webpage that talks about this situation and describes the problem of w and L not being parallel. But I am finding it hard to extract what information to show that this is true. Here is the link: http://sites.isel.ipl.pt/fisica/pedagogia/ajp75(2007)53.pdf
I am concentrating on the first question first so any help would be greatly appreciated.
