Question

1.Two masses of 4gm and 6gm respectively are attached to the ends of a light rod of negligible mass and the rod rotates anticlockwise at the rate of 2rev/sec about an axis passing through the center of mass and perpendicular to its length.
Calculate
(a)the angular momentum of each mass about the center of mass.
(b) the total momentum of the system about the center of mass.
(c) the angular momentum of the system about the axis of rotation.
How will things change if the axis of rotation were inclind at 30 degrees to the length of the rod and why?
