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 decreasing the radius increases angular velocity and kinetic energy while conserving angular momentum.
