Question

Atmosphere pressure is about 100000 Pa. Calculate the force of the Atmosphere on a person whose Surface area is 2.0m

Answer 1

Answer:

The force of the atmosphere 200 KN.

Explanation:

Pressure is the ratio of force applied to the area  to which the force is applied.

i.e Pressure = $\frac{Force}{Area}$

But, Pressure = 100000 pa (100000 N/ $m^{2}$), and surface area = 2.0 $m^{2}$

Thus,

100000 = $\frac{Force}{2.0}$

⇒ Force = 100000 x 2.0

              = 200000

Force = 200 KN

The force of the atmosphere 200 KN.
