A) \[-\frac{({{\mu }_{y}}-1)}{({{\mu }_{y}}'-1)}\]
B) \[\frac{({{\mu }_{y}}'-1)}{({{\mu }_{y}}-1)}\]
C) \[({{\mu }_{y}}'-1)\]
D) \[({{\mu }_{y}}-1)\]
Correct Answer: A
Solution :
Since \[A({{\mu }_{y}}-1)+{A}'({{\mu }_{y'}}-1)=0\Rightarrow \frac{{{A}'}}{A}=-\left( \frac{{{\mu }_{y}}-1}{{{\mu }_{y'}}-1} \right)\]You need to login to perform this action.
