Question

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

Answer 1

The force of the atmosphere 200 KN.

Step-by-step explanation:

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

i.e Pressure =
`(Force)/(Area)`

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

Thus,

100000 =
`(Force)/(2.0)`

⇒ Force = 100000 x 2.0

= 200000

Force = 200 KN

The force of the atmosphere 200 KN.
