A wire with current i = 3.00 A is shown in Fig. 29-53. Two semi-infinite straight sections, both tangents to the same circle, are connected by a circular arc that has a central angle θ and runs along the circumference of the circle. The arc and the two straight sections all lie in the same plane. If B = 0 at the circle's center, what is θ?
