A particle passes through a mass spectrometer as illustrated in the figure below. The electric field between the plates of the velocity selector has a magnitude of 7830 V/m, and the magnetic fields in both the velocity selector and the deflection chamber have magnitudes of 0.0907 T. In the deflection chamber the particle strikes a photographic plate 58.0 cm removed from its exit point after traveling in a semicircle. (a) What is the mass-to-charge ratio of the particle? (b) What is the mass of the particle if it is doubly ionized? (c) What is its identity, assuming it's an element? (Enter the name of an element.)
