AIIMS 2017 Physics Vertical Loops Assertion Reason Question
Assertion: For looping a vertical loop of radius , the minimum velocity at the lowest point should be .
Reason: In this even the velocity at the highest point will be zero.
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
In a vertical loop, the velocity of an object at the highest point is not zero; instead, it must be sufficient to provide the necessary centripetal force to counteract gravitational force. Therefore, while the assertion may be true, the reason provided is false, making option D the correct choice. Other options may incorrectly assert that both the assertion and reason are true or that both are false, which misrepresents the dynamics of motion in a vertical loop. Understanding the relationship between gravitational force and centripetal force is crucial in analyzing motion in circular paths.
