Question

2. A force of 10 N acts on an area of 0.1 m2. The force is kept the same but the area is reduced to half. Which of the following is true?
The pressure doen't change
The pressure reduces to half
The pressure increases by 1.5 times
The pressure doubles

Answer 1

Answer:

Explanation:Pressure = Force/Area

In case 1 --›

Force = 10N

Area = 0.1m²

Pressure = 10/0.1

= 100N/m²

= 100 Pa

In case 2 --›

Force = 10N

Area = 0.05m²

Pressure = 10/0.05

= 200N/m²

= 200 Pa

That means pressure got doubled!

Answer 2

Answer:

Explanation:

The pressure does not change
