A man of weight \(50 \mathrm{~kg}\) carries an object to a height of \(20 \mathrm{~m}\) in a time of \(10 \mathrm{~s}\). The power used by the man in this process is \(2000 \mathrm{~W}\), then find the weight of the object carried by the man (take, \(g=10 \mathrm{~ms}^{-2}\) )
- A \(100\ kg\)
- B \(25\ kg\)
- C \(50\ kg\)
- D \(10\ kg\)
Answer & Solution
Correct Answer
(C) \(50\ kg\)
Step-by-step Solution
Detailed explanation
\begin{aligned} & \text { } \mathrm{P}=\mathrm{w} / \mathrm{t} \\ & \mathrm{w}=\mathrm{p} \times \mathrm{t} \\ & \Rightarrow \quad(\mathrm{m}+\mathrm{M}) \mathrm{gh}=2000 \times 10 \\ & \Rightarrow \quad(\mathrm{m}+50) 200=2000 \times 10 \\ & \Rightarrow \quad \mathrm{m}+50=100…
