Transcribed Image Text:Fig.1
A current i = 38 mA is flowing through the two infinitely long straight wire segments connected by a semi-circular arc, as depicted in the figure.
The semi-circular arc has a radius R= 17 mm - Point A is equidistant from both the infinitely long straight wire segments and also very far away

Note: If the value of current given in the question is positive, then direction of current flow will be the same as depicted in the figure. For the negative
value of current, the direction of current flow will be opposite to the direction shown in the figure.
