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` or `m=(Pxxt)/(gxxh)`
`m=(2000Wxx60s)/(10 m s^(-2)xx10 m)`=1200 kg = 1200 litre
