Question

a
A flying plane with a total surface area of 200 m2., air acts on the plane body with a force
of 8000000N. Find the air
pressure.

Answer 1

The pressure of the air is 40000N/m².

To calculate the pressure of the plane, we use the formula below.

Formula:

• P = F/A................. Equation 1

Where:

• P = Pressure of the air
• F = Force on the plane
• A = Total surface area of the plane.

From the question,

Given:

• F = 8000000 N
• A = 200 m²

Substitute these values into equation 1

• P = 8000000/200
• P = 40000 N/m².

Hence, The pressure of the air is 40000N/m².
