Two long parallel wires are separated by 2.0 cm. The current in one of the wires is three times the other current. If the magnitude of the force on a 2.0-m length of one of the wires is equal to 60 mN, what is the greater of the two currents?
 a. 2.0 A
  b. 1.0 A
  c. 3.0 A
  d. 9.0 A
  e. 1.5 A

 a. 0.20 A
  b. 0.40 A
  c. 40 mA
  d. 20 mA
