A) \[\frac{1}{2}\]
B) \[\frac{1}{4}\]
C) 2
D) \[\frac{1}{5}\]
Correct Answer: B
Solution :
\[\frac{{{\delta }_{a}}}{{{\delta }_{w}}}=\frac{{{(}_{a}}{{\mu }_{g}}-1)}{{{(}_{w}}{{\mu }_{g}}-1)}\]\[=\frac{\left( \frac{3}{2}-1 \right)}{\left( \frac{3/2}{4/3}-1 \right)}=4\]\[\Rightarrow {{\delta }_{w}}=\frac{{{\delta }_{a}}}{4}\]You need to login to perform this action.
