The maximum acceleration with which a body of mass \(200 \mathrm{~kg}\) is lowered into a well using a rope having a breaking force of \(50 \mathrm{~kg}\)-wt is
(Acceleration due to gravity \(=10 \mathrm{~ms}^{-2}\) )
- A \(7.5 \mathrm{~ms}^{-2}\)
- B \(5 \mathrm{~ms}^{-2}\)
- C \(3 \mathrm{~ms}^{-2}\)
- D \(2.5 \mathrm{~ms}^{-2}\)
Answer & Solution
Correct Answer
(A) \(7.5 \mathrm{~ms}^{-2}\)
Step-by-step Solution
Detailed explanation
\(\begin{gathered}200 \mathrm{~g}-\mathrm{T}=200 \mathrm{a} \\ 2000-500=200 \mathrm{a} \\ \Rightarrow \mathrm{a}=\frac{1500}{200}=7.5 \mathrm{~m} / \mathrm{s}^2\end{gathered}\)
