A mass spectrometer is used to examine the isotopes of uranium. Ions emerge from the velocity selector at a speed of 3.00 x 10^5 m/s and enter a uniform magnetic field of 0.600 T directed perpendicularly to the velocity of the ions. What is the distance between the impact points formed on the photographic plate by singly charged ions of 235U and 238U?
