NEET 2026 Physics Free Fall MCQ Question
When a ruler falls vertically, 5 different persons catch it with different reaction times. (g = 9.8 m s⁻²)
A. Person A has reaction time of 0.20 s.
B. Person B has reaction time of 0.22 s.
C. Person C has reaction time of 0.18 s.
D. Person D has reaction time of 0.19 s.
E. Person E has reaction time of 0.21 s.
What is the correct order of the distance travelled by the ruler for each person?
B > E > A > C > D
C > D > A > B > E
B > E > A > D > C
C > D > A > E > B
Correct Answer
Detailed Explanation
There will be a large distance for large reaction time. Descending order of reaction time is tₑ > tᵦ > tₐ > tₒ > t꜀. Descending order of distance covered is Sₑ > Sᵦ > Sₐ > Sₒ > S꜀.
