Determine the mass of the ion

Reference no: EM13492999

In a Mass Spectrometer, ions of a precisely selected speed are sent into a uniform magnetic field where they move along a semicircle and then strike a photographic plate or a detector array, making a mark. A careful measurement of the distance of the mark from the entrance slit gives us the diameter (and the radius) of the circular motion of the ion in the magnetic field, and from that the mass can be calculated. Suppose that the magnetic field in the mass spectrometer is 0.050 T. Suppose that an ion of charge e and speed 4.0x104m/s is found to strike the photographic plate at a distance of 0.332 m from the entrance slit. What is the mass of the ion?
