AP EAMCET · PHYSICS · Motion In One Dimension
The ratio of the displacements of a freely falling body during second and fifth seconds of its motion is
- A \(1: 1\)
- B \(2: 5\)
- C \(4: 25\)
- D \(1: 3\)
Answer & Solution
Correct Answer
(D) \(1: 3\)
Step-by-step Solution
Detailed explanation
\(h_n = \frac{1}{2}g(2n-1)\) \(h_2 : h_5 = (2 \times 2 - 1) : (2 \times 5 - 1)\) \(h_2 : h_5 = 3 : 9\) \(h_2 : h_5 = 1 : 3\)
