AIIMS 2018 Physics Conservation Laws Assertion Reason Question
Assertion: A satellite is orbiting around a planet then its angular momentum is conserved.
Reason: Linear momentum conservation leads to angular momentum conservation.
Both assertion and reason are true, and reason is the correct explanation for assertion.
Both assertion and reason are true, but reason is not the correct explanation for assertion.
Assertion is true, but reason is false.
Both assertion and reason are false.
Correct Answer
Detailed Explanation
The assertion that a satellite's angular momentum is conserved while orbiting a planet is true because there are no external torques acting on the system. However, the reason provided is false; conservation of linear momentum does not inherently lead to conservation of angular momentum, as they are independent principles. Option B is incorrect because while both statements are true, the reason does not explain the assertion. Options C and D are incorrect as they misrepresent the truth of the assertion and reason. Understanding these concepts is crucial in analyzing motion in gravitational fields, where angular momentum plays a key role in orbital dynamics.
