A thin circular ring of mass M and radius R is
rotating in a horizontal plane about an axis vertical
to its plane with a constant angular velocity o. If
two objects each of mass m be attached gently to
the opposite ends of a diameter of the ring, the
ring will then rotate with an angular velocity :-
ωM
@(M – 2m)
(1)
(2)
M + m
M + 2m
(3)
ωM
M + 2m
(4)
@(M+2m)
