    A water pump of power 2kW is installed in a home. Then, the amount of water (in litres) it can raise in one minute to a height of 10m is [Take \[g=10\,m/{{s}^{2}}\]]

    A)  200L            

    B)  1200L

    C)  800L            

    D)  350L

    Correct Answer: B

    Solution :

    Power \[=\frac{mgh}{t}\] \[\Rightarrow \] \[m=\frac{P\times t}{gh}\] \[\Rightarrow \] \[m=\frac{2\times {{10}^{3}}\times 60}{10\times 10}=1200\,kg\] Volume \[=\frac{Mass}{Density}=\frac{1200}{{{10}^{3}}}=1.2\,{{m}^{3}}\] Volume \[=1.2\,{{m}^{3}}=1.2\times {{10}^{3}}L=1200\,L\]
