How much water a pump of 2 kW can raise in one minute to a height of 10 m? (take g = 10 m/s²) (a) 1000 litres (b) 1200 litres (c) 100 litres (d) 2000 litres

Answer: (b). Work done in time t: Pt = mgh. m = Pt/gh = (2000 × 60)/(10 × 10) = 1200 kg 1 kg of water is 1 litre, so the answer is (b) 1200 litres.
