Rotational MotionHard
Question
A thin ring of mass M and radius r is rotating about its axis with constant angular velocity ω. Two objects each of mass m are attached gentely to opposite ends of a diameter of the ring. The ring now rotates with angular velocity given by
Options
A.
B.
C.
D.
Solution
As no external torque is acting about the axis, angular momentum of system remains conserved
I1ω1 = I2ω2
⇒ ω2 =
I1ω1 = I2ω2
⇒ ω2 =
