Given:
The pressure inside the tank, P=74000 Pa
The area of the top of the tank, A=0.38 m²
To find:
The force exerted on the top of the tank.
Explanation:
The pressure can be described as the force exerted per unit area.
Thus the pressure inside the tank is given by,
[tex]P=\frac{F}{A}[/tex]Where F is the force exerted on the top of the tank.
On substituting the known values,
[tex]\begin{gathered} 74000=\frac{F}{0.38} \\ \implies F=74000\times0.38 \\ =28120\text{ N} \end{gathered}[/tex]Final answer:
Thus the force exerted on the top of the tank is 28120 N
