JEE Main Physics question
The power of a pump, which can pump 200 kg of water to a height of 200 m in 10 sec, is (g = 10 m/s²)
Answer: (A)
Solution
P = mgh/t = (200×10×200)/10 = 40000 W = 40 kW.
The power of a pump, which can pump 200 kg of water to a height of 200 m in 10 sec, is (g = 10 m/s²)
P = mgh/t = (200×10×200)/10 = 40000 W = 40 kW.
