Question

The surface area of an object is 100metre square and a force of 10 Newton is applied on it then what is the pressure

Answer 1

Answer:

0.1 pascal

Explanation:

Given :

Surface area of the surface = 100 m²

Force applied = 10 Newtons

To find:

Pressure on the surface

Pressure = force/area

Pressure = 10N/100m²

Pressure = 0.1 N/m²

1 N/m²= 1 pascal

So pressure = 0.1 pascal

The pressure applied on the surface is equal to 0.1 pascal

Note : pressure units can be N/m², N/cm², N/mm²...

Answer 2

$\bigstar \;\;\underbrace{\bf{Pressure=\dfrac{Force}{Area}}}$

The SI unit of Pressure is Newton / Sq. meters = N/m²

Note : 1 N/m² = 1 Pascal

Given ,

Surface area of an object , A = 100 m²

Force applied , F = 10 N

Now , " Pressure is defined as Force acting per unit area "

⇒ P = F / A

⇒ P = 10 / 100

⇒ P = 0.1 Pascal

So the Pressure applied is 0.1 pascal .
