Two long straight aluminum wires, each of diameter 0.40 mm,
carry the same current but in opposite directions. They are
suspended by 1.0-m-long strings as shown in the figure. If the
suspension strings make an angle of 4.0° with the vertical and
are hanging freely, what is the current in the wires? (density
of aluminum = 2.7 g/cm³, g=9.80 m/s?)
