Physics And Measurement Question 268

Question: The unit of the coefficient of viscosity in S.I. system is

Options:

A) m/kg-s

B) $ m-s/kg^{2} $

C) $ kg/m-s^{2} $

D) kg/m-s

Show Answer

Answer:

Correct Answer: D

Solution:

[d] $ F=6\pi \eta vr\Rightarrow \eta =F/6\pi vr $
$ \therefore $ Unit of coefficient of viscosity in S.I. system $ kg/m-s. $
