Question

How does the pressure change if area of contact is doubled keeping the force constant , calculate

Answer 1

We know that

Pressure = Force / Area

So P = F/A

Given F= F, A = 2 A

NOW P 1= F / 2 A

= 1/2( F / A)

= 1/2 P

So pressure gets halved.

Answer 2

Presure = force÷ area
If area is doubled then, force is halved
