Part 2 - Mass Spectrometer Simulation Open the following simulation: Mass and Spring (iwant25tudy.org) The simulation has two sections. The first section is called the velocity selector and the second section is the mass differentiator. Make adjustments to the electric field and magnetic field in the first section so that the charged particle passes through the opening on the rig ht. Verify that v = EIB. Next select a magnetic field in the second region so that the particle moves in a semicircle. Verify that qu = mv. Choose a second magnetic field for section 2 and again verify that qu = mv Change the charge or mass of the particle and repeat the steps above
