Question

Part 2. Please answer only three of the four following problems. If you attempt all four, you MUST indicate which problem you do not wish to have graded. You must show all your work, including definitions of symbols (if not obvious), diagrams with labels, and arithmetic steps to the solution. The numerical answer alone will not be worth full credit. Each of these problems is worth 20 points 5. Keep at least 4 digits in your calculations in this problem. In the early days of controlled nuclear fission, it was useful to separate two different isotopes of uranium in a process called uranium enrichment Generally speaking, 235U was desired over 3U.Suppose a mass spectrometer was used to separate these isotopes.If a uranium ion beam was produced (U') and accelerated through a 10.3keV potential difference, (a) what are the speeds of 23 U and 2U'? (b) What is the difference in diameter of the path these ions take in the presence of a 1.2T magnetic field? (c) If you wanted to separate these ions more by increasing the diameter of their paths in the magnetic field, would it be better to increase the accelerating voltage or increase the magnetic field?
