A man is standing at the edge of a circular plate which is rotating with a constant angular speed about a perpendicular axis passing through the centre. If the man walks towards the axis along the radius, its angular velocity

View answer and explanation

Correct option: C

Increases

Option C (Increases) is correct because as the man walks towards the axis, the moment of inertia decreases, and angular velocity increases to conserve angular momentum.
