Q1. In a mass spectrometer, if an operator wishes to increase the radius of the circular path for a specific ion, which adjustment should be made?
Answer: Decrease the magnetic field strength
Explanation: Decreasing the magnetic field H increases the radius r, as m/e equals (H^2 r^2) / 2E; increasing E would decrease r.
