figure 1 shows part of a mass spectrometer. the whole arrangement is in a vacuum. negative ions of mass 2.84 x 10-20 kg and charge -2.0 x 10-19 c are produced at s, which is at a potential difference of - 3000 v. the ions are accelerated in a narrow beam towards h, a hole in a hollow metal container. inside the container, the negative ions enter a region where an electric field of strength e and a magnetic field of strength 0.83 t act.

is it possible for the io
ns to exit slit p without being deflected in the fields?
explain, with the aid of diagram.
