A motor of power 10 kW is used to pump water from a well 20 m deep . Calculate the efficiency of the motor if it pumps 200 kg of water every minute . Take `g = 10 m//s^(2)`

Explanation

To solve the problem step by step, we will calculate the efficiency of the motor that pumps water from a well.

### Step 1: Understand the given data
- Power of the motor (P_input) = 10 kW = 10,000 W
- Depth of the well (d) = 20 m
- Mass of water pumped per minute = 200 kg
- Time (t) = 1 minute = 60 seconds
- Acceleration due to gravity (g) = 10 m/s²
