Assertion: When a diver dives, the rotational kinetic energy of diver increases, during several somersaults.
Reason: When diver pulls his limbs, the moment of inertia decreases and on account of conservation of angular momentum his angular speed increases.
Text Solution
Verified by ExpertsThe correct answer is:
A
The diver does work by pulling his limbs and thus, 
increases or rotational kinetic energy increases.
