two straight conductors are separated by a distance of 0.75cm. if the first wire carries a current of 6.5 A towards the page, and the magnetic field of the two currents in Point P at 1.5 cm is 0, what current and direction should the second wire have so that this can happen? (please state magnitude and direction of current)

Two straight conductors are separated by a distance of 0.75 cm. If the first wire carries a current of 6.5 A towards the page, and the magnetic field of the two currents at a point P at 1.5 cm is zero, what current and direction must the second lead wire have for this to occur. Clarification (apart from the magnitude and the unit should say the direction of the current)
