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 litre

B

1000 litre

C

100 litre

D

1200 litre

Text Solution

Verified by Experts

The correct Answer is:
D
`P=(mgh)/t= (Vrhogh)/t`
`implies V =(Pt)/(rhogh)=(2xx10 xx60)/(1000 xx10 xx10) = 1.2 m^3`
`=1200 cm^3 =1200` litre
