Correct Answer - Option 3 : Axis of rotation
CONCEPT:
Angular Momentum
- It is the property of a rotating body and it is defined as the product of the moment of inertia and the angular velocity of the rotating object.
- It is a vector quantity
\(\Rightarrow \vec{L}=I\times\vec{\omega}\)
where I = moment of inertia and ω = angular velocity
EXPLANATION:
- Mathematically, the angular momentum is written as
\(\Rightarrow \vec{L}=I\times\vec{\omega}\) -----(1)
- Since the angular velocity acts along the axis of rotation, so by equation 1 it is clear that the angular momentum will also act along the axis of rotation.
- Hence, option 3 is correct.
