An engine pumps up 100 kg water through a height of 10 m in 5s. Given that the efficiency of the engine is 60%. If g = 10 m/s2, then the power of the engine is

The correct option is A 3.3 kWTotal work done = 100*10*10 = 10000 J(60/100)* Actual work = 10000Actual work = 105/6 = 100/6 kJTime = 5s Total Power = 20/6 = 10/3 kW

The correct option is A
3.3 kW

Total work done = 1001010 = 10000 J
(60/100)* Actual work = 10000
Actual work = 10⁵/6 = 100/6 kJ
Time = 5s
Total Power = 20/6 = 10/3 kW
