Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R
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.

View answer and explanation

Correct option: D

Both A and R is correct and R is the correct
explanation of A

Option D (Both A and R is correct and R is the correct explanation of A) is correct because Pascal's principle explains how pressure applied to a fluid is transmitted undiminished, which is why squeezing a tube results in toothpaste coming out the other end.
