1. The problem statement, all variables and given/known data Chlorine has two stable isotopes, 35Cl and 37Cl. Chlorine gas which consists of singly ionized ions is to be separated into its isotopic components using a mass spectrometer. The magnetic field strength in the spectrometer is 1.2 T. What is the minimum value of the potential difference through which these ions must be accelerated so that the separation between them, after they complete their semicircular path, is 1.1 cm? 2. Relevant equations r = mv/qB 3. The attempt at a solution Using the difference in the radii of the semicircles I found the velocity of the particles to be 6.36*10^7 m/s which does not seem correct. Even if I assume the velocity is correct how do I find the potential difference through which the particle was accelerated?
