Question

The amount of pressure exerted by the atmosphere on a 1 m x 1 m table is as high as it is equivalent to the weight of nearly 10 cars. Why do we not get crushed under this high pressure?

• A. Because the internal pressure of our body is more than the atmospheric pressure.
• B. Because the internal pressure of our body is less than the atmospheric pressure.
• C. Because the internal pressure of our body is equal to the atmospheric pressure.
• D. Because it is only applied to our head.

Answer 1

The correct option is C Because the internal pressure of our body is equal to the atmospheric pressure.

The atmospheric pressure outside our body presses inward. Also, there exists a pressure inside our body and this pressure presses outward. Both the pressures are equal but opposite in direction. So, they cancel out the effect of each other and hence we don't feel any force.
