Question

What will be the new pressure if area of contact is quadrupled and force applied is halved?​

Answer 1

Answer:

Pressure is defined as  force acting on a unit area of the object.

pressure=Force/ area

Pressure depends on two factors:

a) Force applied

b) Area over which force acts.

1) When area is doubled : [keeping force constant]

P=F/A ----(1)

If A=2A then P1=F/2A=1/2(F/A)=P/2

When area is doubled , the impact on pressure acting on a object will be decreased .

2)If area is halved: [keeping the force constant]

If A=A/2

then P2=F/A/2=2P

If area is halved, then the impact of pressure acting on the object will be increased.
