NEET 2026 Physics question
When a ruler falls vertically, 5 different persons catch it with different reaction times. () 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?
Answer: (3)
Solution
The ruler falls freely from rest, so the distance fallen before it is caught is , which increases with the reaction time . Order of reaction times: B (0.22) > E (0.21) > A (0.20) > D
