Given below are two statements: One is labelled as Assertion \(A\) and the other is labelled as Reason \(R\). Assertion \(A\) : Product of Pressure \((P)\) and time \((t)\) has the same dimension as that of coefficient of viscosity. Reason \(R\) : Coefficient of viscosity \(=\frac{\text { Force }}{\text { Velocity gradient }}\) Question : Choose the correct answer from the options given below
Pick an option to check your answer.
Answer & Solution
Correct Answer
(C) \(A\) is true but \(R\) is false.
Step-by-step Solution
Detailed explanation
Pressure and time
\(P : \frac{ N }{ m ^{2}}, \text { Time : Sec }\)
\(Pt =\frac{ Nsec }{ m ^{2}}\)
\(\eta=\frac{ F }{6 \pi r v}: \frac{ N }{ m \cdot m / sec }: \frac{ Nsec }{ m ^{2}}\)
