A charged particle of charge q > 0 is sent with velocity ~v into a region of uniform electric field E~ (the velocity and electric field are perpendicular). a) We now turn on a uniform magnetic field in the region; the particle will experience both an electric and magnetic force. What direction should the magnetic field be pointed so that the particle’s velocity remains unchanged? Justify your answer.
