A mass spectrometer is being used to separate common oxygen 16 from the much rarer oxygen 18 taken from a sample of old glacial ice. (The relative abundance of these oxygen isotopes is related to climatic temperature at the time the ice was deposited.) The ratio of the masses of these two ions is 16 to 18 the mass of oxygen 16 is 2.66 x 10-26 kilogram, and they are singly charged and travel at 4.68 x 106 meter per second in a 1.41 T magnetic field. Determine the separation between their paths when they hit a target after traversing a semicircle?
