Question

Assertion [A]: A boy feels more pain when he falls down on a hard concrete floor than when he falls on the sand floor
Reason [R]: Every action has equal and opposite reaction. The time of impact of cement floor is smaller compared to that of sand floor

• A. [A] and [R] are true and [R] is correct explanation of [A]
• B. [A] and [R] are true and [R] is not correct explanation of [A]
• C. [A] is true and [R] is false
• D. [A] is false, and [R] is true

Hint:

In assertion-reason questions, check if the reason directly explains the assertion; correct statements may not always provide the correct explanation.

Answer 1

The Correct Option is B

Step 1: Analyzing the assertion.
The boy feels greater pain on a hard floor because the stopping time is shorter, producing a larger average force.

Step 2: Analyzing the reason.
The reason mentions Newton's third law and shorter impact duration on hard ground; while factually correct, it doesn't fully encompass the energy absorption aspect explaining the pain.

Step 3: Connecting A and R.
Both statements are true individually, but R does not serve as the complete explanation for A.

Step 4: Conclusion.
Hence, option (2) is the correct choice.
