The figure shows the cross section through three long wires with a linear mass distribution of \( 145 \mathrm{~g} / \mathrm{m} \). They carry currents \( i_{1}, i_{2} \), and \( i_{3} \) in the directions shown. Wires 2 and 3 are \( 13.9 \mathrm{~cm} \) apart and are attached to a vertical surface, and each carries a current of 797 A. What current, \( i_{1} \), will allow wire 1 to "float" at a perpendicular distance \( d=10.5 \mathrm{~cm} \) from the vertical surface? (Neglect the thickness of the wires.)
