Question

If a weight of 150 N is applied on a surface of area 10cm×10cm, calculate the pressure acting on the surface. (with explanation)

Answer 1

Answer:

Given:-

Weight of object = 150 N

Surface Area = 10×10 cm = 10×10/100 m

= 1 m

To Find:-

Pressure acting on the object

Sol;

Pressure of a given object

= Area of object in metre/Weight in Newton

= N/m²

= 1/150 N/m². ans......

Answer 2

Concept:

• Force
• A force is an effect that can alter an object's motion according to physics.
• Pressure
• The force delivered perpendicularly to an object's surface per unit area across which that force is dispersed is known as pressure.
• In comparison to the surrounding pressure, gauge pressure is the pressure.
• Pressure is expressed using a variety of units.

Given:

• Weight = 150 N
• Surface area = 10cm ×10cm = 100 cm² = 0.01 m²

Find:

• The pressure acting on the surface

Solution:

We know that pressure is the force acting per unit of area

P = F/A

Here, the force is the weight

P = W/A
P = 150 N /0.01m²

P = 15000 Pa

The pressure acting on the surface is 15000 Pa.
