A) \[500\sqrt{2}{{\mu }_{0}}\]
B) \[300\sqrt{2}{{\mu }_{0}}\]
C) \[200\sqrt{2}{{\mu }_{0}}\]
D) \[250\sqrt{2}{{\mu }_{0}}\]
Correct Answer: D
Solution :
Here, \[n=100\]turns/m, \[i=5\]amp, \[\theta ={{45}^{o}}\] Using the relation, \[B=\frac{{{\mu }_{0}}ni}{2}\] \[(\cos 45+\cos 45)\] or \[B=\frac{{{\mu }_{0}}\times 5\times 100}{2}\left( \frac{1}{\sqrt{2}}+\frac{1}{\sqrt{2}} \right)\] or \[B=250\sqrt{2}{{\mu }_{0}}\]You need to login to perform this action.
