Problem

Two identical straight conductors X and Y, each of length L carrying the same current I, are placed in a uniform magnetic field B. Conductor X is aligned parallel to the magnetic field lines, while conductor Y is perpendicular to them. Which of the following correctly states the magnitudes of the forces FXF_X and FYF_Y on the conductors? (a) FX=0,  FY=ILBF_X = 0,\; F_Y = I L B (b) FX=ILB,  FY=0F_X = I L B,\; F_Y = 0 (c) FX=FY=ILBF_X = F_Y = I L B (d) FX=FY=0F_X = F_Y = 0
