Assertion: A satellite is orbiting around a planet then its angular momentum is conserved.

Reason: Linear momentum conservation leads to angular momentum conservation.

View answer and explanation

Correct option: C

If Assertion is correct but Reason is incorrect.

Option C is correct. The assertion is true because the angular momentum of a satellite orbiting a planet is conserved due to the central force. The reason is incorrect because linear momentum is not conserved due to the continuously changing direction of velocity.
