Work done= mgh(g=10)
100kg×10m/s×20=20000J
Power=work done/time
=20000/10
=2000W

answer is 2000w
mass of the water which was lifted by the pump,m=100kg
height of the water tank,h=20m
Time taken to fill the tank,t=10s
Acceleration due to gravity,g=10m/sec^2
therefore,using this formulae,
workdone:-mgh(g=10)
100kg×10m/s×20
=20000j
power=workdone/time
=20000/10
2000w
