Answer 1

Explanation:

Just try to understand that,

P = F/A

For an instant, let F = 10N, and area = 5m²

Then P1 = 10/5 = 2N/m²

Now let the force be same as before and area get decreased by 50%.

F = 10N

A = 2.5m²

Then,

P2 = 10/2.5 = 4N/m²

Now on comparing P1 and P2,

P1 = 2N/m² , A = 5m²

P2 = 4N/m² , A = 2.5m²

Now you can see that if area decreases, the pressure increases.

Note: Area is inversely proportional to pressure, at a constant force applied.

Answer 2

Answer:

Pressure is force per unit area.

If you apply a force of 10 N on an area of 10 square metre, the pressure is 1 N per square metre.

If you apply the same force on an area of 1 sqaure metre, the pressure is 10 N per square metre.

So, for the same force, if the area decreases, the pressure increases. It does not decrease.
