AIIMS 2019 Physics Impulse and Momentum Assertion Reason Question
Force exerted by concrete floor is more because change in momentum is fast.
Both assertion and reason are true and reason is the correct explanation of assertion.
Both assertion and reason are true but reason is not the correct explanation of assertion.
Assertion is true but reason is false.
Both assertion and reason are false.
Correct Answer
Detailed Explanation
The assertion that the force exerted by a concrete floor is more because the change in momentum is fast is false; the force is actually determined by the rate of change of momentum, which is not inherently greater in this scenario. Additionally, the reason provided is also false, as the force exerted by the floor is not solely dependent on the speed of momentum change but rather on the interaction of the objects involved and their respective masses. Options A and B are incorrect because they assert the truth of both statements, while option C incorrectly claims the assertion is true. Understanding the relationship between force, mass, and acceleration (F = Δp/Δt) is crucial in clarifying these concepts.
