How much pressure is exerted on the head of a nail when it is struck with a force of 50 N and area of contact is 0.00002 m2?​

Force ,F = 50 N

Area on which force act ,A = 0.00002 m²

Pressure is exerted on the head of nail,P

We have to calculate the pressure exerted on the head of a nail when force of 50 N is applied on nail and the area of contact with nail is 0.00002 m².

As we know that Pressure is calculated by the force acting per unit area.

where,

P denote pressure

A denote area on which the force acted

F denote force

Substitute the value we get

⟹ P = 50/0.00002

⟹ P = 50×100000/2

⟹ P = 25×100000

⟹ P = 2500000 Pa

Hence, the pressure exerted on the tip of the nail is 2500000 Pascal or 2500 KiloPascal.

The pressure exerted on the tip of the nail is 2500000 Pascal
