We use a mass spectrometer to isolate ?C from "C isotopes to carbon-date an artifact. Carbon atoms are ionized (+e) and sent into a velocity selector with electric field strength E=2×10° V/m. 1. The first stage is getting a beam of particles with the same velocity, independent of mass. a. Given the picture to the right, write a force equation for the velocity selector. b. What magnetic field is required to select single-ionized charged particles with speed v=1.1x10' (m/s)?
