Assertion: A man sitting on a rolling table, when he stretches his arms horizontally, his speed is reduced.
Reason: Principle of conservation of angular momentum is applicable in this situation.

View answer and explanation

Correct option: A

If both assertion and reason are true and reason is the correct explanation of assertion

Option A (If both assertion and reason are true and reason is the correct explanation of assertion) is correct because stretching arms increases moment of inertia, decreasing angular speed to conserve angular momentum.
