Question: The amount of meat in prehistoric diets can be determined by measuring the ratio of the isotopes nitrogen-15 to nitrogen-14 in bone from human remains. Carnivores concentrate 15N, so this ratio tells archaeologists how much meat was consumed by ancient people. Suppose you use a velocity selector to obtain singly-ionized (missing one electron) nitrogen atoms of speed 8.50 km/sand bend them along a semicircle within a uniform magnetic field. The 14N atoms travel along a semicircle with a diameter of 30.0 cm . The measured masses of these isotopes are 2.32Ã-10âˆ'26 kg (14N) and 2.49Ã-10âˆ'26 kg for (15N).
Part A) Find the separation of the 14N and 15N isotopes at the detector.
