MCQ
The power of pump, which can pump $200 kg $ of water to a height of $50 m$ in $ 10 sec, $ will be
- ✓$10 \times {10^3}\,watt$
- B$20 \times {10^3}\,watt$
- C$4 \times {10^{3\,}}watt$
- D$60 \times {10^3}\,watt$
✓
Answer
Correct option: A.
$10 \times {10^3}\,watt$
a
(a)$P = \frac{W}{t} = \frac{{mgh}}{t} = \frac{{200 \times 10 \times 50}}{{10}}$$ = 10 \times {10^3}\,W$
(a)$P = \frac{W}{t} = \frac{{mgh}}{t} = \frac{{200 \times 10 \times 50}}{{10}}$$ = 10 \times {10^3}\,W$
