A "mass spectrometer" measures the ratio m/q for ions by first accelerating them from rest though an electric potential V, then putting them into a region with a magnetic field perpendicular to their motion. We can use this information to figure out what chemical species are present in a sample, even at extremely low concentrations. a) Show that the velocity v of an ion after acceleration is 2qV/m. b) Show that m B2 2 9 2V c) In a device with accelerating voltage V = 1000 volts and magnetic field B = 0.1 Tesla, some ions are observed to have a radius of curvature of 6.44 cm. Make a hypothesis as to what the ions are. (There is more than one possible answer; any are ok.)
