.What is pressure? What is the relation of pressure with area which it is applied?
Answers
Answer:
1.Pressure, in the physical sciences, the perpendicular force per unit area, or the stress at a point within a confined fluid. ... In SI units, pressure is measured in pascals; one pascal equals one newton per square metre. Atmospheric pressure is close to 100,000 pascals.
2.Since we found F = PA, we see that the force exerted by a pressure is directly proportional to the area acted upon as well as the pressure itself. The force exerted on the end of the tank is perpendicular to its inside surface. This direction is because the force is exerted by a static or stationary fluid.
Answer
If the force decrease then the pressure also decrease vice versa, SI unit of force is Newton and that pressure is pascal . pressure is inversely proportional to the area, if the area is less than pressure will be more. if the area is more then pressure will be less
