20) A positively-charged particle is moving southward in a downward-directed uniform magnetic field. The magnetic force is the only force, if any, acting on the particle. Describe the trajectory of the particle, assuming it remains in the uniform magnetic field, and its elevation does not change. A. The particle will keep on going straight for a while and then begin to curve rightward. B. The particle will keep on going straight for a while and then begin to curve leftward. C. The particle will curve rightward along a parabolic trajectory. D. The particle will curve leftward along a parabolic trajectory. E. The particle will travel clockwise, as viewed from above, around a horizontal circle. AB. The particle will travel counterclockwise, as viewed from above, around a horizontal circle
