Assertion: As star collapse its angular velocity increases.
Reason: The mass of star decreases.
Reason: The mass of star decreases.
View answer and explanation
Correct option: C
If Assertion is True but the Reason is False
Option C (If Assertion is True but the Reason is False) is correct because as a star collapses, its moment of inertia decreases, causing its angular velocity to increase due to conservation of angular momentum, but the mass of the star does not decrease significantly during the collapse.
