A) \[{{\mu }_{0}}\frac{i}{4R}\]
B) \[{{\mu }_{0}}\frac{5i}{4R}\]
C) \[{{\mu }_{0}}\frac{3i}{4R}\]
D) \[{{\mu }_{0}}\frac{i}{2R}\]
Correct Answer: C
Solution :
\[{{B}_{1}}=\frac{{{\mu }_{0}}\times 2i}{2\times R}\] Similarly, \[{{B}_{2}}=\frac{{{\mu }_{0}}i}{4R}\] \[{{B}_{net}}=\frac{{{\mu }_{0}}i}{R}-\frac{{{\mu }_{0}}i}{4R}=\frac{{{\mu }_{0}}i}{2R}\]You need to login to perform this action.
