Keeping the horizontal velocity constant, Alexa varies both the electric and magnetic fields as the charged particle is moving between the plates. What can Jeremiah say about what he observes as a consequence? "When the particle is in motion, it is impossible to alter its path." "When the particle is in motion, it is possible to bring it to a complete stop in between the two plates by varying the electric and magnetic fields." "When the particle is in motion, it is only possible to deflect it upwards." "It is possible to direct the motion of the particle by varying the electric and magnetic fields
