A) \[{{\mu }_{0}}\]
B) \[3{{\mu }_{0}}\]
C) \[6{{\mu }_{0}}\]
D) \[2{{\mu }_{0}}\]
E) zero
Correct Answer: A
Solution :
Amperes law states that the line integral of\[\overrightarrow{B}\] around any closed path or circuit is equal to\[{{\mu }_{0}}\]times the total current crossing the area bounded by the closed path provided the electric field inside the loop remain constant. Thus, \[\int{\overrightarrow{B}}.\overrightarrow{dl}={{\mu }_{0}}{{i}_{net}}\] \[={{\mu }_{0}}(3-2)={{\mu }_{0}}\]You need to login to perform this action.
