The pressure of water on the ground floor is 40,000 Pa and on the first floor is 10,000 Pa. Find the height of the first floor. (Take : density of water = `1000 "kg m"^(-3) , g=10 "m s"^(-2)` )

Explanation

To find the height of the first floor based on the given pressures, we can follow these steps:

### Step 1: Understand the relationship between pressure, height, and density
The pressure difference between two points in a fluid can be expressed using the formula:
\[ \Delta P = \rho g h \]
where:
- \(\Delta P\) is the difference in pressure,
- \(\rho\) is the density of the fluid,
...
