Question

The force of 11.75 N through an area of 80 cm2.Calculate the pressure.

Answer 1

Given:-

• Force ,F = 11.75 N

• Area , a = 80cm²

To Find:-

• Pressure , p

Solution:-

Firstly we convert the area into metre square.

1m² = 10⁴ cm²

∴ 80cm² = 80/10000 m² = 0.008m²

As we know that

→ Pressure = Force/area

Substitute the value we get

→ p = F/a

→ p = 11.75/0.008

→ p = 1468.75 Pa.

∴ The pressure acting on the area is 1468.75 Pascal.

Additional Information !!

✧ Product of mass and acceleration is called force.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀OR

A push or pull of an object is called force.

✧ SI unit of Force is Newton.

✧ It is denoted by N.

✧ Force is vector Quantity i.e., both Magnitude and direction.

✧ Mathematical term

⟹ Force = Mass×Acceleration
