The power of a water pump is 2 kW. If `g = 10 m//s^2,` the amount of water it can raise in 1 min to a height of 10 m is :

A

2000 L

B

1000 L

C

100 L

D

1200 L

Text Solution

Verified by Experts

The correct Answer is:
D
`P=(W)/(t)=(mgh)/(t)`
`2000=(mxx10xx10)/(60)`
`m=1200kg`
Density of water `=1000(kg)/(m^3)`
Volume of water `=(m)/(1000)=1.2m^3`
`=1.2xx1000=1200L`
