If momentum \([ P ]\), area \([ A ]\) and time \([ T ]\) are taken as fundamental quantities, then the dimensional formula for coefficient of viscosity is :
- A \(\left[ PA ^{-1} T ^{0}\right]\)
- B \(\left[ PA T ^{-1}\right]\)
- C \(\left[ PA ^{-1} T \right]\)
- D \(\left[ PA ^{-1} T ^{-1}\right]\)
Answer & Solution
Correct Answer
(A) \(\left[ PA ^{-1} T ^{0}\right]\)
Step-by-step Solution
Detailed explanation
Viscosity \(=\) pascal.second \(P ^{ x } A ^{ y } T ^{z}=\left[ M ^{1} L ^{-1} T ^{-1}\right]\) \(\left[ M ^{1} L ^{+1} T ^{-1}\right]^{ x }\left[ L ^{2}\right]^{y}\left[ T ^{1}\right]^{z}= M ^{1} L ^{-1} T ^{-1}\)…
