Density, Compressibility & Pascal's Law
Given below are two statements: one is labelled as Assertion and the other is labelled as Reason
Assertion A: When you squeeze one end of a tube to get toothpaste out from the other end, Pascal's principle is observed.
Reason R: A change in the pressure applied to an enclosed incompressible fluid is transmitted undiminished to every portion of the fluid and to the walls of its container.
In the light of the above statements, choose the most appropriate answer from the options given below
Show answer and solution
Answer: (d)
- Squeezing one end raises the pressure, and that pressure is transmitted through the paste to the open end, pushing it out: Pascal's principle. A is correct.
- R is the statement of Pascal's law, which is correct and explains A.
- So the answer is (d).
