Question

In `cgs` system , the unit of coefficient of viscosity is poise`(P)`. One poise is equivalent to
A. `10 kg m^(-1) s^(-1)`
B. `1 kg m^(-1) s^(-1)`
C. `10^(-1) kg m^(-1) s^(-1)`
D. `10^(2) kg m^(-1)`

Answer 1

Correct Answer - C
`1 P = 1 dyn s cm^(-2)`
` = 1 g cm^(-1) s^(-1)`
` = 10^(-1) kg m^(-1) s^(-1)`
i.e., `1 P = 1//10 th` of the `SI unit`.
