Question

Force = 80N
Avea = 20 cm2
Then,
Pressure = ?​

Answer 1

Answer:

there fore pressure=80/20=4

Answer 2

Answer :

➥ The pressure = 40000 N/m²

Given :

➤ Force = 80 N

➤ Area = 20 cm²

To Find :

➤ Pressure = ?

Required Solution :

For solving this question, let's first know about Pressure.

The force exerted perpendicularly on a unit area is called Pressure.

• The SI unit of Pressure is Pascal.
• The SI base unit of Pressure is N/m².
• Pressure is represented by P.

✒ To find the Pressure, first we need to convert the Area cm² to m² to convert cm² to m² divide the area value by 10000, then after we will find the Pressure.

→ Area = 20 m²

→ Area = 20/10000

→ Area = 0.002 m²

Now, we have Force, and it's Area,

• Force = 80 N
• Area = 0.002 m²

We can find Pressure by using the formula of pressure which says P = F/A.

Here, $\:$

• P is the Pressure in N/m².
• F is the Force in N.
• A is the Area in m².

✎ So let's find Pressure (P) !

$\tt{:\implies P = \dfrac{F}{A}}$

$\tt{:\implies Pressure = \dfrac{Force}{Area}}$

$\tt{:\implies Pressure = \cancel{\dfrac{80}{0.002}}}$

$\bf{:\implies \underline{\:\: \underline{\red{\:\:Pressure = 40000\: N/m^2\:\:}}\:\:}}$

║Hence, the Pressure is 40000 N/m².║
