Question

a force of 25N act over an area of 100cm×100cm.calculate the pressure exercted

Answer 1

1m=10000cm =(100×100)cm. P=F/A. Therefore pressure =(25/1)Pa =25Pa

Answer 2

Answer :

Given -

Force = 25 N

Area = (100×100) cm² = 10000 cm² = 1 m²

To Find -

Pressure ?

Solution -

Pressure is said to be Force per unit area.

Pressure = Force/Area.

Pressure = 25/1 = 25 N/m²

Hence, Pressure = 25 N/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.
