A pump can take out 7200 kg of water per hour from a well 100 m. deep. The power of pump, assuming its efficiency as `50%` will be

Explanation

To find the power of the pump, we will follow these steps:

### Step 1: Calculate the work done by the pump in lifting the water.
The work done (W) in lifting the water can be calculated using the formula:
\[ W = mgh \]
where:
- \( m \) = mass of water (in kg)
- \( g \) = acceleration due to gravity (approximately \( 10 \, \text{m/s}^2 \))
