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 10²⁵ kg and 3.95*10²⁵ k g , respectively, and they travel at 2.3 *10⁵ m/s in a 0.2 T field. What is the separation between their paths (in mm) when they hit a target after traversing a semicircle?
