The potential energy of the water is converting into electric energy by making it to fall from a height of 100 m . How many 60 W bulbs can be lit by this electric energy if `2xx 10^(6)` kg of water is falling in 1 hour .

Explanation

To solve the problem step by step, we need to calculate the potential energy of the water falling from a height and then determine how many 60 W bulbs can be powered by that energy.

### Step 1: Calculate the Potential Energy (PE)
The formula for potential energy is given by:
\[ PE = mgh \]
Where:
- \( m \) = mass of the water (in kg)
- \( g \) = acceleration due to gravity (approximately \( 9.8 \, \text{m/s}^2 \))
