Question

A force of 25N acts on an area of 25cm2 . calculate the pressure produced

Answer 1

pressure=force/area
p=25/25
pressure=1Pa
SI unit of pressure is pascal

Answer 2

Answer:

The pressure that is produced due to the force is $10000$ $N/m^{2}$.

Explanation:

• The pressure is the force acting on a unit area surface.
• For a particular value of force, the pressure is greater if the surface area is reduced.
• Units of pressure are Pascal $(Pa)$ or $N/m^{2}$.

The formula of pressure is:

$Pressure=\frac{Force}{Area}$

In the given question, force's magnitude is $25$ $N$.

The area $=25$ $cm^{2}$

               $= \frac{25}{10^{4} }$ $m^{2}$

               $=0.0025$ $m^{2}$

So, the pressure produced $=\frac{25 N}{0.0025 m^{2} }$

                                             $= 10000$ $N/m^{2}$

Hence, the pressure produced due to the force is $10000$ $N/m^{2}$.
