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
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
Reason [R]: Every action has equal and opposite reaction. The time of impact of cement floor is smaller compared to that of sand floor
Show Hint
In assertion-reason questions, check if the reason directly explains the assertion; correct statements may not always provide the correct explanation.

- [A] and [R] are true and [R] is correct explanation of [A]
- [A] and [R] are true and [R] is not correct explanation of [A]
- [A] is true and [R] is false
- [A] is false, and [R] is true
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the assertion.
The boy experiences more pain on the hard floor because the force of impact is larger due to smaller deformation and shorter impact time.
Step 2: Understanding the reason.
The reason states Newton's third law and shorter impact time on hard floor; while correct, it does not fully explain why the pain is more—force and energy absorption also play a role.
Step 3: Relation between A and R.
Both statements are true individually, but R is not the complete explanation of A.
Step 4: Conclusion.
Hence, the correct choice is option (2).
