Question

Atmospheric pressure is about 500 000 Pa. Calculate the force of the atmosphere on a person whose surface area is 5.0 sq. m.

Answer 1

Provided that:

• Pressure = 5,00,000 Pascal
• Area = 5 metre sq.

To calculate:

• The force

Solution:

• The force = 25,00,000 N

Using concept:

• Pressure formula

Using formula:

• P = F/A

Where, P denotes pressure, F denotes force and A denotes area.

Required solution:

→ Pressure = Force/Area

→ P = F/A

→ 5,00,000 = F/5

→ 5,00,000 × 5 = F

→ F = 25,00,000 N

→ Force = 25,00,000 Newton

Answer 2

• Pressure=500000Pa
• Area=5m^2

We know

$\boxed{\sf Pressure=\dfrac{Force}{Area}}$

$\\ \sf\longmapsto Force=Pressure\times Area$

$\\ \sf\longmapsto Force=500000\times 5$

$\\ \sf\longmapsto Force=25,00000N$

$\\ \sf\longmapsto Force=2500kN$
