A) 5/2
B) 7/3
C) 4/3
D) 5/3
Correct Answer: B
Solution :
\[B=\frac{{{\mu }_{0}}}{2\pi (d/2)}({{i}_{1}}-{{i}_{2}})=20\] \[B=\frac{{{\mu }_{0}}}{2\pi (d/2)}({{i}_{1}}+{{i}_{2}})=50\] \[\frac{{{i}_{1}}-{{i}_{2}}}{{{i}_{1}}+{{i}_{2}}}=\frac{2}{5}\]Treading\[\frac{{{i}_{1}}}{{{i}_{2}}}=x\]\[x=\frac{7}{3}\]You need to login to perform this action.
