A) 40 kW
B) 80 kW
C) 4000 kW
D) 960 kW
Correct Answer: A
Solution :
From the relation,\[Power\,P=\frac{work}{time}=\frac{mgh}{t}\]\[\left( \begin{align} & Given:mass\,of\,water\,m=200\,kg \\ & height\,h=\,200\,m \\ & time\,t=10\,s \\ & g=10\,m/{{s}^{2}} \\ \end{align} \right)\] Putting the given value in Eq. (1), we have\[=\frac{200\times 10\times 200}{10}=40000\,\text{watt = 40}\,\text{kW}\]You need to login to perform this action.
