Please solve these question in detail. Thanks so much in advance.

A wire with current i = 9.41 A is shown in the figure. Two semi-infinite straight sections, both tangent to the same circle with radius 1.22 cm, are connected by a circular arc that has a central angle 0 and runs along the circumference of the circle. The connecting arc and the two straight sections all lie in the same plane. If B = 0 at the center of the circle, what is 0? Connecting arc Number i Units The figure shows wire 1 in cross section; the wire is long and straight, carries a current of 4.03 mA out of the page, and is at distance d1 = 2.71 cm from a surface. Wire 2, which is parallel to wire 1 and also long, is at horizontal distance d2 = 5.11 cm from wire 1 and carries a current of 6.99 mA into the page. What is the x component of the magnetic force per unit length on wire 2 due to wire 1? -d2 Number Units
