A man standing on a platform holds weights in his outstretched arms. The system is rotated about a central vertical axis. If the man now pulls the weights inwards close to his body, then

View answer and explanation

Correct option: D

All of the above

Option D (All of the above) is correct because when the man pulls the weights inwards, his moment of inertia decreases, leading to an increase in angular velocity and kinetic energy while conserving angular momentum.
