Question

Define Pressure and write the SI unit of pressure. A force of 100 N is
applied on an area of 4 m2. Calculate the pressure being applied on the
area.

Answer 1

Answer:

Pressure is the amount of force applied perpendicular to the surface of an object per unit area and the for it is p (or P). The SI unit for pressure is the pascal (Pa), equal to one newton per square metre (N/m2, or kg·m−1·s−2).

Answer 2

Pressure is the amount of force applied perpendicular to the surface of an object per unit area and the for it is p (or P). The SI unit for pressure is the pascal (Pa), equal to one newton per square metre (N/m2, or kg·m−1·s−2).

Given, force=100N

and area

$4 ^{2}$

∴pressure=

area/force

=

4m

2

100N

=25Pa
