Question

how would pressure change if area is doubled keeping force constant​

Answer 1

Answer:

When the surface area is doubled, keeping the force constant, the pressure will decrease

Answer 2

Answer:

Pressure is defined as the force acting per unit area of a surface. It is always perpendicular to the surface.

Hence, P = F/A

Here, P is the pressure exerted per unit area of a surface of total area A due to a force F.

Let P be the initial pressure on area A due to constant force F

P = F/A

Let P' be the pressure when the area of contact is doubled

P' = F/2A

Now, dividing these two equations

P/P' = (F/A)/(F/2A)

A bit of mathematics, and

P = 2P'

Or

P' = P/2

Aka, the pressure per unit area gets halved.
