An electrically charged bullet of mass 0.010 kg leaves thebarrel of a gun traveling parallel to the ground and perpendicularto the Earth's magnetic field at 1.400e+3 m/s. Intheory, what charge could the bullet carry in order to remain at aconstant height? Assume that the Earth is flat, and that themagnetic field (0.500 gauss) is horizontal and points left if youare looking in the direction of the bullet's motion.
