The direction of angular velocity vector of a rotating body is along the
Atangent to the path
Baxis of rotation
Cradius vector
Dcentripetal force
Answer & Solution
Correct answer: B. axis of rotation
1. For a rotating rigid body the angular velocity vector lies along the axis of rotation.
2. Its sense follows the right-hand thumb rule: curl fingers along rotation, thumb gives ω direction.
3. Therefore the direction is the axis of rotation.
