Answer 2

We know that Pressure exerted by Fluid is given by :

• P = ρgh

• Where ρ is the Density of the Fluid

• g is the Acceleration due to gravity = 9.8 m/s²

• h is the depth of the Fluid

Given Height of the Tank = 2m

Pressure exerted by water in the Rectangular tank at the bottom is :

⇒ P = 1000 × 9.8 × 2 = 19600 N/m²

We know that Thrust is the Force acting Normally to a Surface and Pressure is Thrust Force acting per unit Area.

⇒ $Pressure = \frac{Thrust}{Area}$

⇒ $Thrust = Pressure \times Area$

⇒ Given the Base Area = 100 m²

⇒ Thrust = 19600 × 100 = 1960000 = 1.96 × 10⁶ Newton
