Question

.if 20 Newton of force is acting on a rectangular surface of length 20 cm and 30 cm then find the pressure ​

Answer 1

Solution:

Given,

• Force = 20N
• Length of rectangular surface = 30cm
• Breadth of rectangular surface = 20cm

To find,

• Pressure

___________________________

Firstly finding area of rectangular surface

Area of rectangle = length × breadth

Ar(rectangle) = 30 × 20

Ar(rectangle) = 600 cm²

Converting to m²

Ar(rectangle) = 0.6 m²

Using the formula

P = F/A

Where

• P : pressure = ?
• F : force = 20N
• A : area = 600 cm²

Substituting the values we have

→ P = 20/0.6

→ P = 20/(6/10)

→ P = 200/6

→ P = 33.33 Pascal (N/m²)

Hence , pressure acting of the rectangular surface = 33.33pa
