Two wires parallel to each other and separated by a distance d carry different currents; they exert a force with magnitude F on each other.

(a) The wires carry current in opposite directions. If the current carried by both wires is divided by five and the distance between the wires is divided by three, then what will the force's magnitude be (as a multiple of F)?

(b) The wires carry current in the same direction . If the current carried by one of the wires is divided by five and the distance between the wires is divided by five, then what will the force's magnitude be (as a multiple of F)?
