A mass spectrometer is a machine used to measure mass of small charged particles. Mass spectrometers have three main sections an accelerator, a velocity selector, and a detection chamber.

Numerical Response 3. The electron from the mass spectrometer above is replaced with a different charged particle with mass 2.66 x 10-26 kg and charge of -2e. The potential difference accelerates the new charged part to a speed of 1.55 x 105 m/s and the particle enters the detection chamber. Determine the radius of curvature of the particle's path if the magnetic field strength is 0.800 T. The radius of curvature the charged particle in the detection chamber is a.bc x 10d m. The values of a, b, c, and d, are , and (Record all four digits of your answer in the numerical-response section on the answer sheet.) Use the following information to answer the next
