A) \[{{7}^{o}}\]
B) \[{{10}^{o}}\]
C) \[{{12}^{o}}\]
D) \[{{5}^{o}}\]
Correct Answer: B
Solution :
For without deviation \[\frac{A}{A}=\frac{\mu -1}{\mu -1}\] \[\frac{{{15}^{o}}}{A}=\frac{1.75-1}{1.5-1}\] \[\frac{15}{A}=\frac{0.75}{0.50}\] \[A=\frac{0.50\times 15}{0.75}={{10}^{o}}\]You need to login to perform this action.
