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 = (W)/(t) = (mgh)/(t) or m = (Pt)/(gh) = ((2000W)(60s))/((10m//s^2)(10m)) = 1200kg = 1200 litre` (as mass of 1 litre of water is kg)
