Mass spectrometer You are using a mass spectrometer to analyze the composition of a protein. After digesting the protein down to amino acids (of mass m), the amino acids are vaporized and singly ionized (giving them a charge +q); the charged amino acids are accelerated by an electric field E over a distance d, after which they enter a region of uniform magnetic field. After a half-circle, they hit a position-sensitive detector a distance x from their entry point. acceleration region bending region E O V O B E O K d Cup-o-amino acids X O O O In Part A, you will work through the physics of a mass spectrometer. In part B, you will apply your result to deduce the composition of a protein from the mass spec output.Part A. 1. What is the speed v of the singly charged amino acids as they exit the acceleration region? Give your answer symbolically in terms of m, d, q and E. 2. What is the position x at which singly charged amino acids hit the detector, as a function of m, d, q, E and B? 3. How does x scale with the mass to charge ratio? That is, what is n in x o (m/q)"
