Question

3) A daredevil decides to lay on a bed of nails for his audience. If the amount of pressure
on each nail is 30 Pa, pushing with a force of 0.04 N, what is the area of each nail?​

Answer 1

¶Given¶

• Pressure ,P = 30 Pa

• Force ,F = 0.04 N

¶To Find¶

• Area of nail on which force is acting ,A

¶Solution¶

As we know that Pressure is defined as force per unit area.

P = F/A

• A = F/P

Substitute the value we get

→ A = 0.04/30

→ A = 0.004/3

→ A = 0.0013 m²

Therefore, the area on which force was acting is 0.0013m².

Additional Information!!

•Product of mass and acceleration is called force.

•SI unit of Force is Newton.

• It is denoted by N.

• Force is vector Quantity i.e., both Magnitude and direction.

Mathematical term

• F = ma

where

F is the Force

m is the mass

a is the acceleration .
