Pascal's law is valid, only when the fluid is_____________________?
Correct answer: B. At rest
- A. Frictionless and at rest
- B. At rest
- C. At rest and when the frictionless fluid is in motion
- D. None of these
Explanation
Pascal's law is a hydrostatic principle stating that pressure applied to a confined fluid at rest is transmitted undiminished in all directions. A moving fluid introduces velocity and friction effects, so the simple law is not applied directly.
