Question

A certain laboratory has two sets of magnets. Each set is capable of creating a region of uniform magnetic field of strength 1 T. In addition, the laboratory has two sets of large chargeable plates that can be used to create constant electric fields. You are to construct a device that is to separate 12C from 14C for radioactive dating. (You have an oven that can create slow moving positive ions of these isotopes.) You can use one set of plates to accelerate the ions, the other set of plates and a magnet to select one velocity, and the other magnet as a mass spectrometer. Design and sketch the overall apparatus. Your design needs to specify the values of the voltage difference across the accelerator plates, the electric field in the set of plates used as part of the velocity selector, and the size of your mass spectrometer. Using your design parameters predict the spatial separation of the two isotopes when they exit the mass spectrometer
