Question

A man exerts a pressure of 20Pa by applying force of 25N on a box . Find out the area over which force is applied?

Answer 1

Answer:

pressure=force/area

=> 20=25/area

=> area=25/20

=> 1.25 m^2

Answer 2

Answer :

Given -

• Force = 25 N
• Pressure = 20 Pa

To Find -

• Area over which force is applied ?

Solution -

Pressure is said to be Force per unit area.

Pressure = Force/Area.

⇒ 20 = 25/Area

⇒ 20*Area = 25

⇒ Area = 25/20

⇒ Area = 1.25 m²

Hence, Area over which force is applied = 1.25 m².

Some Additional Information :

• Weight is the force with which it is attracted towards the earth.

• Mass is the measure of its inertia.

• Thrust is the perpendicular force to the surface is called thrust.

• Pressure is defined as force upon area.

• Pressure = Thrust or Force/Area.
