18 A rigid rectangular loop, which measures 0.30 m by 0.40 m, carries a current of 9.9 A. A uniform external magnetic field of magnitude 1.8 T in the negative x-direction is present. Segment CD is in the x-z plane and forms 19° with the z-axis. The y-component of the magnetic force on segment AB is closest to:(A)zero(B)-5.1 N(C)-1.7 N(D)+5.1 N(E)+1.7 N
