The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Fluid statics deals with the behavior of fluids at rest.
A fundamental law governs how pressure is transmitted through a static fluid.
Step 2: Detailed Explanation:
The statement in the question is the definition of Pascal's Law (formulated by Blaise Pascal).
Pascal's Law states that the pressure applied to a confined fluid at rest is transmitted undiminished in all directions throughout the fluid.
This means that at any specific point within a static liquid, the intensity of pressure is equal in all directions (isotropic pressure).
Let us compare this with the other principles:
- Archimedes Principle: Relates to the buoyant force exerted on a body immersed in a fluid.
- Bernoulli's Principle: Relates to the conservation of energy in a flowing fluid.
- Continuity Principle: Relates to the conservation of mass in a fluid flow system.
Therefore, the correct law is Pascal's Law.
Step 3: Final Answer:
The principle described is Pascal's Law.
