    Two long conductors separated by a distance ' dd ' carry currents ' I1I_{1} ' and ' I2I_{2} ' in the same directions. They exert a force ' FF ' on each other. The distance between them is increased to ' 3d3d '. If new repulsive force of magnitude ' 23 F\frac{2}{3}\text{ }F ' is found between these conductors, the required change in the magnitude and direction of one of the currents in the conductor is respectively [length of the conductors is constant]
