Water is filled in a flask up to a height of 20 cm. The bottom of the flask is circular with radius 10 cm. If the atmospheric pressure is `1.01xx10^5` Pa, find the force exerted by the water on the bottom. Take `g=10 ms^-2` and density of water =1000 kgm^-3.

Explanation

To solve the problem, we need to find the force exerted by the water on the bottom of the flask. We will follow these steps:

### Step 1: Calculate the pressure at the bottom of the flask
The pressure at the bottom of the flask can be calculated using the formula:
\[ P = P_{\text{atmospheric}} + \rho g h \]

Where:
- \( P_{\text{atmospheric}} = 1.01 \times 10^5 \, \text{Pa} \)
