Question

a force of 10 N acts on an area of 0.1msquare.If the force is kept the same but the area is reduced to half, how does the pressure change?

Answer 1

the pressure will increase as pressure us inversly
propotional to area and directly propotional to force,here as the area is cut to half the pressure will be double of before

Answer 2

Pressure = Force / Area

Here, force is constant.
So, pressure is inversely proportional to Area.

As area is reduced to half, pressure will be doubled.

Initially, P = 10/0.1 = 100 Pa

Now, finally pressure becomes 200 Pa.


So, change in pressure is
∆P = 200 - 100 = 100 Pa
