A mass spectrometer is used to examine the isotopes of uranium. Ions in the beam emerge from the velocity selector at a speed of 2.17 × 105 m/s and enter a uniform magnetic field of 0.293 T directed perpendicularly to the velocity of the ions. The charge on the singly charged ion is 1.60218 × 10-19 C, and the atomic mass unit is 1.66054 × 10-27 kg.
What is the distance between the impact points formed on the photographic plate by singly charged ions of 235 U and 238 U? Answer in units of cm.
