Question

Shanky exerts a pressure of 28 Pa by applying a force of 14N on a box. Calculate the area over which the force is applied.​

Answer 1

Answer :

• Area over which the force is applied is 0.5 m².

Explanation :

Given :

• Pressure exerted by Shanky, P = 28 Pa
• Force applied by Shanky, F = 14 N

To find :

• Area on which the force is applied, A = ?

Knowledge required :

Formula for pressure :

⠀⠀⠀⠀⠀⠀⠀⠀⠀P = F/A

Where,

• P = Pressure
• F = Force
• A = Area

Solution :

By using the formula for pressure and substituting the values in it, we get :

⠀⠀=> P = F/A

⠀⠀=> 28 = 14/A

⠀⠀=> A = 14/28

⠀⠀=> A = 1/2

⠀⠀=> A = 0.5

⠀⠀⠀⠀⠀⠀⠀∴ A = 0.5 m²

Therefore,

• Area on which the force is applied, A = 0.5 m²

Answer 2

Answer:

$\huge \fbox {Question}$

Shanky exerts a pressure of 28 Pa by applying a force of 14N on a box. Calculate the area over which the force is applied.

$\huge \bf \: To \: find$

Force applied

$\small \red{ \sf \: firstly \: lets \: understand \: the \: concept}$

There is a box in which Shanky exert a pressure of 28 Pa and she applied 14 N. And we have to find how much force has been applied.

$\huge \bf \: Formula$

$\huge \bf \: P \: = \frac{F}{A}$

Here,

P = Pressure

F = Force

A = Area

Calculations

$\sf \implies \: 28 = \dfrac{14}{a}$

$\sf \implies \: a \: = \dfrac{14}{28}$

$\sf \implies a \: = \dfrac{1}{2}$

Now,

We must convert them into decimal
