Question

How would the pressure change if the area is doubled keeping the trust constant?

Answer 1

When the surface area is doubled, keeping the force constant, the pressure will decrease. b] When the force is doubled, keeping the area constant, pressure will increase.

Answer 2

Explanation:

The thrust acting on an object per unit area is called the pressure on the surface. Mathematically, it can be written as :

$P=\dfrac{F}{A}$

Where,

F is the thrust or the force acting

A is the area

So, it is clear that the pressure is inversely proportional to the area.

If the area is doubled keeping the thrust constant, the pressure would be half as :

$P'=\dfrac{F}{A/2}=2\ P$

Hence, this is the required solution.
