Question

What is the force required to produce a pressure of 36000pa on an area of 400cm square​

Answer 1

Answer:

p = F/A

F = pA

F = 36000×4

F = 144000 N

Answer 2

Given:

✰ Pressure ( P ) = 36000 Pa

✰ Area ( A ) = 400 cm

To find:

✠ The force required to produce a pressure.

Solution:

Before solving the particular problem or numerical, let's first go through common terms that can be used here!

Pressure:

➛ The normal force acting per unit area on a surface is called pressure.

If is the normal force (F) that is acting on the normal surface area (A), then the pressure exerted on the surface area is given by:

✭ Pressure = Force/Surface Area ✭

We conclude:

• Pressure is directly proportional to thrust or force.
• For a given thrust the pressure is inversely proportional to the surface area of the object in contact.

Let's first convert area into m because while doing calculations, the nature of the units should be same else we will get wrong answer.

⇾1 cm² = 1/(100 × 100) m²

⇾1 cm² = 1/10000 m²

⇾400 cm² = 400/10000 m²

⇾4/100 m²

⇾0.04 m²

Now,

➥ P = F/A

➥ F = P × A

➥ F = 36000 × 0.04

➥ F = 1440 N

∴ The force required to produce a pressure = 1440 N
