A rectangular tank of base area 100 `m^(2)` has a height of 2 m. Calculate the thrust at the bottom of the tank, if it is filled upto the brim with water of density `10^(3)` kg `m^(-3)`.

Explanation

To solve the problem of calculating the thrust at the bottom of a rectangular tank filled with water, we can follow these steps:

### Step 1: Understand the Concept of Thrust
Thrust at the bottom of the tank is the force exerted by the water due to its weight. This can be calculated using the formula:
\[ \text{Thrust} = \text{Pressure} \times \text{Area} \]

### Step 2: Calculate the Pressure at the Bottom of the Tank
The pressure at the bottom of the tank can be calculated using the formula:
