1. A mass spectrometer is an analytical instrument used to separate collection of different atoms and molecules contained within a gaseous sample. First, the atoms/molecules in the sample are positively ionized, then accelerated (from rest) through a potential difference AV. They enter uniform magnetic field where the magnetic force bends the ions into circular trajectories. Because they have different velocities and masses, they will follow different circular arcs and be separated from each other. Consider a mass spectrometer with a 200.00 mT magnetic field directed as shown. A collection of carbon, nitrogen, and oxygen atoms are singlely ionized ( through a 950.00 Volt potential difference. What are the radii of the different trajectories followed by these three ions? Use the following constants: 1 u = 1.6605×10-27kg, e = 1.6022x10-19 C. T
