Unit of viscosity in CGS system is_______________________?
Correct answer: A. gm .cm-1 sec-1
- A. gm .cm-1 sec-1
- B. gm . cm2 . sec-2
- C. gm .cm-2, sec-1
- D. gm . cm . sec-1
Explanation
Dynamic viscosity has dimensions mass per length per time, so in CGS units it is g cm⁻¹ s⁻¹, called the poise. The other expressions do not have the dimensions of viscosity.
