A) \[\frac{{{\mu }_{0}}i}{R}\]
B) \[\frac{{{\mu }_{0}}i}{2R}\]
C) \[\frac{2{{\mu }_{0}}i}{R}\]
D) \[\frac{3{{\mu }_{0}}i}{8R}\]
Correct Answer: D
Solution :
Here, net magnetic field \[B=\frac{{{\mu }_{0}}}{4\pi }\left( \frac{2\pi -\theta )i}{R} \right)\] \[\frac{{{\mu }_{0}}}{4\pi }\frac{\left( 2\pi -\frac{\pi }{2} \right)\times i}{R}=\frac{3{{\mu }_{0}}i}{8R}\] \[\Rightarrow \] \[B+\frac{3\mu d}{8R}\]You need to login to perform this action.
