The image below is a diagram of a mass spectrometer for measuring the mass of an ion. In the figure S is a source of ions which are accelerated with a potential difference V, then enter an area where there is a magnetic field B with speed v. Because v is perpendicular to B, the ion's path is semicircular with radius r and then hits the detector. If B= 80 mT and the potential difference V= 1000 Volts and the ion charge q = 1.6 x 10^-19 C hits the detector at a distance x = 1.6 m. Calculate the mass of the ion I -Detector
