18. A positive charge of 0.300 C moves horizontally due +x at speed 2.50 x 102 m/s. It entered a magnetic field directed towards -y with a magnitude of 0.400 T. What is the magnitude (include unit) and direction of the force on the charge? F = 19. 5.00 A current flows in the +x within a straight horizontal wire, 1.50 m long. The wire is within a magnetic field of magnitude 0.300 T in the +z direction. What is the magnitude (with unit) and direction of force on the wire? F =
