AP EAMCET · PHYSICS · Motion In One Dimension
An airplane flies \(400 \mathrm{~m}\) north and \(300 \mathrm{~m}\) south and flies \(1200 \mathrm{~m}\) upwards, then net displacement is
- A \(1400 \mathrm{~m}\)
- B \(1500 \mathrm{~m}\)
- C \(1200 \mathrm{~m}\)
- D \(1100 \mathrm{~m}\)
Answer & Solution
Correct Answer
(C) \(1200 \mathrm{~m}\)
Step-by-step Solution
Detailed explanation
The various displacements of airplane is shown below Net displacement travelled by airplane, \(\begin{aligned} d & =\sqrt{100^2+1200^2}=\sqrt{1450000} \\ & =1204.16 \mathrm{~m} \simeq 1200 \mathrm{~m} \end{aligned}\)
