A) zero
B) maximum
C) minimum
D) unity
Correct Answer: A
Solution :
From law of conservation of angular momentum, when no external torque acts on a rotating body, then the total angular momentum of the body remains constant. That is, If \[\tau =\frac{dJ}{dt}=0\] \[\Rightarrow \] \[J=I\omega =\text{constant}\] where \[I\]is moment of inertia and cd is angular velocity.You need to login to perform this action.
