An ion that is doubly ionized passes through the velocity selector and into the deflection chamber of a mass spectrometer, as shown below. In the velocity selector the electric field has a magnitude of 8039 V/m, and the magnitude of the magnetic field in both the velocity selector and the deflection chamber is 0.0919 T. If in the deflection chamber the ion is detected at a distance of 39.6 cm from its entry point, determine the following. O O O O O - O (a) mass-to-charge ratio of the ion 2.10-07 kg/C (b) mass of the ion 6.720-26 kg (c) identity of the lon, assuming it's an element (Use only the masses of elements in their most common form as listed on the periodic table of elements.)
