A mass spectrometer (see diagram) is an analytic device used to identify various charged particles by
measuring their charge to mass ratio. The charged particles are accelerated through a potential difference
AV, and they enter a region of uniform magnetic field. The field bends the ions into circular trajectories,
but after just half a circle they either strike the wall or pass through a small opening to a detector. As the
accelerating voltage is slowly increased or decreased, different charged particles reach the detector and are
measured. The diagram shows the set-up for detecting positive charges, but it can be easily adjusted to
detect negative charges (by reversing the polarity of the accelerating potential and reversing the direction of
the B-field). So we'll assume that the necessary adjustments have been made in this question if we are
talking about negative charges rather than positive ones.
