Hint: The unit of the dynamic viscosity is known as poise which is generally expressed in a centimeter-gram-second system of units. The force needed to maintain a unit is being expressed by the poise. With the metric prefix centi- the poise is being often used. In the SI unit a centipoise is one millipascal-second.
Complete step by step solution:
Let's discuss the option given.
OPTION A.
\[0.001\] pascal second: Since, \[1\] pascal second is equivalent to \[10\] poise. Therefore, \[1\] poise = \[0.1\] pascal second. Hence, The option \[0.001\] is incorrect.
OPTION B.
\[0.0001\] pascal second: Since, \[1\] pascal second is equivalent to \[10\] poise. Therefore, \[1\] poise = \[0.1\] pascal second. Hence, The option \[0.0001\] is incorrect.
OPTION C.
\[0.01\] pascal second: Since, \[1\] pascal second is equivalent to \[10\] poise. Therefore, \[1\] poise = \[0.1\] pascal second. Hence, The option \[0.01\] is incorrect.
OPTION D.
\[0.1\] pascal second: Since, \[1\] pascal second is equivalent to \[10\] poise. Therefore, \[1\] poise = \[0.1\] pascal second. Hence, The option \[0.1\] is correct.
Hence, The option D: \[0.1\] pascal second is the correct answer.
Note: Poise is the equality or the equal distribution of weight and a state of balance or equilibrium. Viscosity is measured in terms of a ratio of shearing stress to the velocity gradient in a fluid.
