Question : Which law was developed in the 1600s to describe that any force applied to a confined fluid is transmitted equally in all directions, regardless of the shape of the container?
Option 1: Magnus's law
Option 2: Graham's law
Option 3: Pascal's law
Option 4: Torricelli's law
Correct Answer: Pascal's law
Solution : The correct option is Pascal's law.
The external static pressure given to a confined liquid "is distributed or transmitted evenly throughout the liquid in all directions," as stated by Pascal's law.
According to Blaise Pascal, a pressure change at any point in a confined, incompressible fluid is transmitted throughout the fluid, so that change occurs everywhere. This principle is known as Pascal's law, Pascal's principle, or the principle of transmission of fluid pressure.
