A mass spectrometer is designed to calculate masses of atoms. A source produces positive ions of mass m and charge q. The ions move with a velocity v to the right, pass through a narrow slit S1 and enter a region between two charged plates. In this region they experience both an electric and a magnetic field. The electric field E is caused by the 2 charged plates; the upper plate is (-) charged and the lower plate is (+)...
