Question

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?​

Answer 1

`\boxed{\large{\bold{\textbf{\textsf{{\color{brown}{Answer}}}}}}:)}`

Given :-

• 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

To Find :-

• Pressure??

Solution :-

We know that

`\boxed{\bold{P = (F)/(A)}}`

where

• P = pressure
• f = force
• a = acceleration

According to the question,

• P = 50/0.00002
• p=50/2/100000
• p=50×100000/2
• P = 2500000 Pa

Answer 2

Given:-

Force ,F = 50 N

Area on which force act ,A = 0.00002 m²

To Find:-

Pressure is exerted on the head of nail,P

Solution:-

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.

P = F/A

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.
