2. The figure at right is a cross section through three long wires withlinear mass density 50.0 g/m. They each carry equal currents I in thedirections shown. The lower two

wires are 4.00 cm apart and areattached to a table. What current I will cause the upper wire toaccelerate upward at 1.00 m/s² when it is 4.00 cm from the other wires(forming an equilateral triangle)?
