Question

What is Pascal’s Law?

(a) For every action, there is an equal and opposite reaction

(b) Force is the time rate of change of momentum

(c) For an ideal gas, the pressure is directly proportional to temperature and constant volume and mass

(d) A pressure change at any point in the fluid is transmitted throughout the fluid such that the same change occurs everywhere

This question was addressed to me at a job interview.

My doubt is from Fluids Mechanical Properties Pressure topic in portion Mechanical Properties of Fluids of Physics – Class 11

Answer 1

The correct answer is (d) A pressure change at any point in the fluid is transmitted throughout the fluid such that the same change occurs everywhere

The best explanation: For every action, there is an equal and opposite reaction – Newton’s Third Law

Force is the time rate of change of momentum – Newton’s Second Law

For an ideal gas, the pressure is directly proportional to temperature and constant volume and mass – Ideal Gas Law

A pressure change at any point in the fluid is transmitted throughout the fluid such that the same change occurs everywhere – Pascal’s Law.
