A) \[\frac{{{\mu }_{0}}i}{r}\]
B) \[\frac{4{{\mu }_{0}}i}{r}\]
C) zero
D) \[\frac{{{\mu }_{0}}i}{4r}\]
E) \[\frac{{{\mu }_{0}}i}{2r}\]
Correct Answer: A
Solution :
At point P, \[{{B}_{net}}={{B}_{AB}}+{{B}_{CD}}\] \[=\frac{{{\mu }_{0}}i}{2r}+\frac{{{\mu }_{0}}i}{2r}=\frac{{{\mu }_{0}}i}{r}\]You need to login to perform this action.
