A metal rod is falling toward the surface of the Earth near the equator. As it falls, one end of the rod becomes positively charged due to the motional emf of the rod through the Earth's magnetic field. The rod is oriented so that the rod is vertical with the positive end higher. the rod is horizontal with the positive end toward the east. the rod is horizontal with the positive end toward the west. the rod is horizontal with the positive end toward the north.
