The figure shows wire 1 in cross section; the wire is long and straight, carries a current of 4.25 mA out of the page, and is at distance d1 = 2.44 cm from a surface. Wire 2, which is parallel to wire 1 and also long, is at horizontal distance d2 = 5.25 cm from wire 1 and carries a current of 6.94 mA into the page. What is the x component of the magnetic force per unit length on wire 2 due to wire 1
