Question 19 (3 points) The operator of a mass spectrometer produces a beam of doubly ionized (2+) ions. They first are accelerated by a potential difference of 34 V. Then, as the ions pass through a magnetic field of 0.050 T, the radius of their path is 53 mm. a) Determine the charge to mass ratio of this ion. (2 marks b) Using your periodic table determine the most likely element this ion would be. (Please note that the average NUCLEON, proton or neutron, has a mass of 1. 67 x10 2 kq.)(1 mark)
