Question

if area decrease, pressure increase for the same force

Answer 1

Pressure increases with decrease in area, provided that the force applied remains constant. Because the relation between pressure and area is Pressure = Force / Area.

Hope it helps you :)

Answer 2

We know that Thrust acting on unit area is called Pressure.

Also, we know that :

a. pressure acting on the surface is inversely proportional to the area of the surface in which force acts .

b. pressure is directly proportional to the applied force.

Hence, in simple words we can say that if area will decrease then there will be increase in pressure even if the applied remain constant.
