Question

The power of pump, which can pump 200 kg of water to a height of 50 m in 10 sec, will be

A

$10 \times 10^{3}watt$

B

$20 \times 10^{3}watt$

C

$4 \times 10^{3}watt$

D

$60 \times 10^{3}watt$

Answer

$10 \times 10^{3}watt$

Explanation

Solution

$P = \frac { W } { t } = \frac { m g h } { t } = \frac { 200 \times 10 \times 50 } { 10 }$ $= 10 \times 10 ^ { 3 } \mathrm {~W}$
