A) 25 D
B) ? 25 D
C) 1 D
D) None of these
Correct Answer: D
Solution :
\[\frac{{{f}_{l}}}{{{f}_{a}}}=\frac{{{(}_{a}}{{\mu }_{g}}-1)}{{{(}_{l}}{{\mu }_{g}}-1)}\] Þ \[\frac{{{f}_{l}}}{{{f}_{a}}}=\frac{_{a}{{\mu }_{g}}-1}{_{l}{{\mu }_{g}}-1}=\frac{1.5-1}{\frac{1.5}{1.6}-1}=\frac{0.5\times 1.6}{-0.1\,}=-\,8\] Þ \[{{P}_{l}}=\frac{{{P}_{a}}}{8}=\frac{5}{8}\]
