A) \[\frac{{{\mu }_{0}}{{l}^{2}}}{\sqrt{2}\pi d}\]
B) \[\frac{{{\mu }_{0}}{{l}^{2}}}{2\pi d}\]
C) \[\frac{2{{\mu }_{0}}{{l}^{2}}}{\pi d}\]
D) \[\frac{\sqrt{2}{{\mu }_{0}}{{l}^{2}}}{\pi d}\]
Correct Answer: A
Solution :
Force between BC and AB will be same in magnitude. \[{{F}_{BC}}={{F}_{BA}}=\frac{{{\mu }_{0}}{{l}^{2}}}{2\pi d}\] \[F=\sqrt{2}{{F}_{BC}}\] \[=\sqrt{2}\frac{{{\mu }_{0}}}{2\pi }\frac{{{l}^{2}}}{d}\] \[F=\frac{{{\mu }_{0}}{{l}^{2}}}{\sqrt{2}\pi d}\]You need to login to perform this action.
