The pressure of the Earth’s atmosphere at sea level is about 100000 Pa. Calculate the force
due to the weight of the air pressing down on a piece of paper 20cm X 30cm lying flat on a
table at sea level.

F = PA
A = 600cm² = 600 x 10^-4 m²
F = 100000 x 600 x 10^-4
= 6 x 10³ N

Answer:
Therefore, area in terms of metres would be=
20/100×30/100(as metres=1/100)
=>0.06m² right,
Now from relation: P=F/A
100000=F/0.06
= 100000×0.06=6000N
