The direction of the angular velocity vector is along

Options

A. the tangent to the circular path
B. the axis of rotation
C. the inward radius
D. the outward radius

Answer

B

Explanation

(b) Angular velocity is the vector quantity which represents the process of rotation (change of orientation) that occurs at as instant of time. For a rigid body it supplements translational velocity of the centre of mass to describe the full motion. The line of direction of the angular velocity is given by the axis of rotation and the right-hand indicates the direction.
