A) \[\frac{{{\mu }_{0}}i}{4\pi r}\,(1+\pi )\]
B) \[\frac{{{\mu }_{0}}i}{2\pi r}\,(1+\pi )\]
C) \[\frac{{{\mu }_{0}}i}{\pi r}\,(1+\pi )\]
D) \[\frac{{{\mu }_{0}}i}{r}\,(1+\pi )\]
Correct Answer: A
Solution :
Here the magnetic field at C, will be as the sum of due to curved part and straight part as, \[B=\frac{{{\mu }_{0}}i}{4r}+\frac{{{\mu }_{0}}i}{4\pi r}=\frac{{{\pi }_{0}}i}{4\pi r}\,\,(1+\pi )\]You need to login to perform this action.
