Answer: Given:
Power of a motor pump, (P) = 2 kW
Height (h) = 10 m
Work done by the pump in raising m mass of the water to a height of 10 m is,

W = = = m g h m \times 10 \times 10 100 m

Water per minute the pump can raise to a height of 10 m,

P = \frac{W}{1 minute} = \frac{W}{60 s} \Rightarrow 2000 = \frac{100 m}{60} \Rightarrow m = \frac{60 \times 2000}{100} \Rightarrow m = 1200 kg

Hence, 1200 kg water can be raised per minute by the pump to a height of 10 m.
