Triply charged uranium-235 and uranium-238 ions are being separated

(a) Triply charged uranium-235 and uranium-238 ions are being separated in a mass spectrometer. (The much rarer uranium-235 is used as reactor fuel.) The masses of the ions are 3.90×10−25 kg and 3.95×10−25 kg,respectively, and they travel at 3.0×105m/s in a 0.250-T field. What is the separation between their paths when they hit a target after traversing a semicircle?
(b) Discuss whether this distance between their paths seems to be big enough to be practical in the separation of uranium-235 from uranium-238.
