A charged particle is shot into a region of magnetic field 4.78 T (into the page) and electric field 79.4 N/C (pointing downward). The velocity of the particle is perpendicular to both fields, and it passes through undeflected (diagram 1a). Now, the magnetic field is removed, and the particle is accelerated through the same potential difference and is shot into the electric field. This time, it travels distance 2.68 cm across, and is deflected by distance 0.184 cm (diagram 1b). Calculate the charge-to mass ration of this particle, in C/kg. Be sure to include the sign.
