Question

What will be effect on pressure as area increases?

Answer 1

Answer:

If Area increases then the pressure decreases

Answer 2

Answer:

Pressure is inversely proportional to the cross-sectional area of the object.

Explanation:

Effect on pressure as area increases

Since we know that $Pressure=\frac{force}{area}$

So,pressure is inversely proportional to the cross-sectional area of the object.

(1)If area decreases then pressure increases and if area increase then pressure decreases.

for example a rocket nozzle having a small cross section for the ejection of high pressurised jets, so that rocket compromise with the newtons third law of motion.
