AIIMS 2018 Physics Conservation of Angular Momentum Assertion Reason Question
Assertion: An ice-skater stretches out arms-legs during performance. Reason: Stretching out arms-legs helps the performer to balance his or her body so that he or she does not fall.
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
Correct Answer
Detailed Explanation
The assertion is true because ice-skaters do stretch out their arms and legs during performances to enhance their balance and control. However, the reason provided is false; while extending limbs can aid in balance, it does not solely prevent falls, as balance also depends on factors like body rotation and center of mass. Option A is incorrect because the reason does not correctly explain the assertion, while option B is also incorrect since the reason is not true. Option D is incorrect because the assertion is indeed true.
