7) Two long parallel wires carry currents in the same direction and they are 9 cm apart. The first wire carries a current of 5.3 A such that the net magnetic field is zero between the two wires at the position of 3.5 cm from the 5.3 A wire. Find the current carried by the second wire. (Express your answer in the unit of A)
