F=100
Newton Area=25 cm^2=0.0025square metre
thrust=100 N
pressure=thrust /area =100/0.0025 Newton per sq.
m =40000 pa
When force is reduced to 25 Newton changed pressure=25/0.0025
=10000 pa 1
Pascal is equal to pressure of 1 Newton per square metre.
Thrust: Force exerted by an object perpendicular to the surface
Pressure: Force exerted by an object per unit area.

FORCE = 100 N
AREA = 25 CM2 than
25 × 1/10000m2 = 1/400m2
PRESSURE = 100/1/400= 40000 pascal
