A) \[N-{{m}^{2}}\]
B) \[N-s\]
C) \[N-s/{{m}^{2}}\]
D) \[N-{{m}^{2}}/s\]
E) \[N-{{m}^{2}}-s\]
Correct Answer: C
Solution :
Coefficient of viscosity is given by \[\eta =\frac{F}{A(\Delta {{v}_{x}}/\Delta z)}\] Its SI unit is \[\frac{N-s}{{{m}^{2}}}\] Another unit of coefficient of viscosity is poise.
