Question

The force due to atmospheric pressure on our head is nearly equal to 2250 N.
Why are we not crushed under this huge force?

• A. Because force due to atmospheric pressure is acting in all directions.
• B. Because the pressure inside our body is also equal to the atmospheric pressure.
• C. Because the force due to atmospheric pressure is negligible.
• D. Because force due to atmospheric pressure acts downward.

Answer 1

The correct option is B Because the pressure inside our body is also equal to the atmospheric pressure.

Force due to atmospheric pressure is too high and can't be neglected. It can easily crush our body. But the pressure inside our body is also equal to the atmospheric pressure from outside and hence these two pressures balance each other.
