Answer:
Atmospheric pressure on the surface of the earth is about 105Nm-2. The average surface area of the body of a common man is about 2m2. Thus the total force o a common man due to atmospheric pressure is =2×105N.

Given:
The area of a common man, A = 2 square metre
To Find:
The force of a common man due to the atmosphere pressure.
Calculation:
- The atmospheric pressure is given as:
A = 1.01325 × 10⁵ Pa.
- The relation between force, area and pressure is given as:
Force = Pressure × Area
⇒ F = 1.01325 × 10⁵ × 2
⇒ F = 2.0265 × 10⁵ N
- So, the force of a common man due to atmosphere pressure is 2.0265 × 10⁵ N.
