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 m 2?

Answer 1

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

$:\implies$ P = 50/0.00002

$:\implies$ P = 50×100000/2

$:\implies$ P = 25×100000

$:\implies$ P = 2500000 Pa

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

Answer 2

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

P = F/A

P = pressure

f = force

a = acceleration

P = 50/0.00002

P = 2500000 Pa
