    Answer:

    Explanation:

    As there is no external torque is applied so the angular momentum remains constant.

    L = I ω = constant

    Where, I is the moment of inertia of the system and ω is the angular velocity

    As we move towards the edge, the moment of inertia increases, hence the angular velocity decreases.
