°°° Solution °°°

Power , P=2 kW

Power , P = Time Taken(T)Work done(W)

⇒W=P×T

For every minute i.e. 60 s, work done by the pump is W=2×1000×60=120000J

Now, this work done is stored in water as it potential energy. Thus, mgh = 120000 J

⇒m= 9.8×10 120000

=1224.5 kg

Hence, 1224.5 kg of water is lifted by the pump every minute to a height of 10 m...
