A) \[\frac{{{\mu }_{0}}I}{4\pi r}\left[ \pi +2+\sqrt{2} \right]\]
B) \[\frac{{{\mu }_{0}}I}{4\pi r}\left[ \pi +\sqrt{2}+\frac{1}{\sqrt{2}} \right]\]
C) \[\frac{{{\mu }_{0}}I}{4\pi r}\left[ \pi +\frac{1}{\sqrt{2}}+2 \right]\]
D) \[\frac{{{\mu }_{0}}I}{4\pi r}\left[ \pi +2+2\sqrt{2} \right]\]
Correct Answer: C
Solution :
\[{{B}_{0}}\] (duetoBCD) \[\frac{{{\mu }_{0}}I\pi }{4\pi r}=\frac{{{\mu }_{0}}I}{4r}\] \[{{B}_{0}}(deu\,\,to\,\,AB)=\frac{{{\mu }_{0}}I\pi }{4\pi r}(\sin 0+\sin \pi /4]\] \[\frac{{{\mu }_{0}}I\pi }{4\pi r}\frac{1}{\sqrt{2}}\] \[\angle ODP=\pi /4\] \[\angle POD=\angle POE=\pi /4\]You need to login to perform this action.
