Question

Calculate the pressure exerted by a force of 12N acting on an area of 100cm square

Answer 1

Explanation:

Pressure = F/A

F=12N

A=100cm sq. = 0.01m sq.

Now ,

P = F/A

=12/0.01

=12×100/1

Pressure =1200 Pascal

Answer 2

When a force of ‘F’ Newton is applied perpendicularly to a surface area ‘A’, then the pressure exerted on the surface by the force is equal to the ratio of F to A. The formula for pressure (P) is:

P = F / A
S.I. unit of pressure is Pascal.
A pascal can be defined as a force of one newton applied over a surface area of a one-meter square
force - The push or pull on an object with mass that causes it to change its velocity is known as force.



Force = 12 N
Area = 100 cm² = 0.01m²


We have to find pressure exerted by force acting per unit area.


Pressure = F/A

F=12N

A=100cm². = 0.01m²

Now ,

P = F/A

=12/0.01

=12×100/1

Pressure =1200 Pascal

12N 100cm² 1200 .
