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