A) \[4{{\mu }_{2}}-{{\mu }_{1}}=3\]
B) \[4{{\mu }_{1}}-{{\mu }_{2}}=3\]
C) \[3{{\mu }_{2}}-{{\mu }_{1}}=4\]
D) \[2{{\mu }_{1}}-{{\mu }_{2}}=4\]
Correct Answer: A
Solution :
[a] \[(\mu -1)t=n\beta \] \[\frac{({{\mu }_{1}}-1)\times 1.8\times {{10}^{-5}}}{({{\mu }_{2}}-1)\times 3.6\times {{10}^{5}})}=\frac{18\beta }{9\beta }\] \[({{\mu }_{1}}-1)=4({{\mu }_{2}}-1)\] \[4{{\mu }_{2}}-{{\mu }_{1}}=3\]
