Question

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R Assertion A: The ideal fluid do not have shear stress. Reason R: The Newtonian fluid is the fluid in which shear stress is not proportional to rate of shear strain. In the light of the above statements, choose the most appropriate answer from the options given below

• A. Both A and R are correct and R is the correct explanation of A
• B. Both A and R are correct but R is NOT the correct explanation of A
• C. A is correct but R is not correct
• D. A is not correct but R is correct

Hint:

For Newtonian fluid: \[ \boxed{ \tau = \mu \frac{du}{dy} } \] For ideal fluid: \[ \boxed{ \mu = 0 \Rightarrow \tau = 0 } \]

Answer 1

The Correct Option is C
