Some mass spectrometers, as shown in the figure, use an electric field to give the incoming lons a certain known kinetic energy as they enter the magnetic field. Assume a magnetic field strength of 0.3 T. (a) If a certain ion carries a charge of 70 C, has a mass of 0.7 g, and possesses an initial kinetic energy of 4 x 10-71, what is the radius r of its circular path? Submit Answer Tries 0/8 (b) What is the final kinetic energy of the ion just before it reaches the ion detector?
