The dimension of dynamic viscosity is__________________?
Correct answer: A. ML-1T-1
- A. ML-1T-1
- B. L2T-1
- C. LT-2
- D. ML-1T-2
Explanation
Dynamic viscosity is shear stress divided by velocity gradient, giving dimensions of pressure multiplied by time: ML⁻¹T⁻¹. L²T⁻¹ is the dimension of kinematic viscosity.
