17 One Of The Applications Of Magnetic Forces And Fields Is The Bainbridge Mass Spectrometer As Shown Schematically I 1 (60.71 KiB) Viewed 46 times

17. One of the applications of magnetic forces and fields is the "Bainbridge Mass Spectrometer" as shown schematically in figure below. As shown, charged particles leave a source and enter a velocity selector (that has electric field E and magnetic field B) where the electric and magnetic forces are balanced, followed by a region of uniform magnetic field Bo where the particle describes a circular path of radius R and is ultimately detected in the detector. J a. Using the concepts of electric, magnetic and centripetal forces, show that the charge-to-mass ratio of the charges detected is given by b. Which of the following is true? i. ii. iii. iv. V. 9 m E BB R Lighter particles describe circle of larger radius before being detected. Heavier particles describe circle of smaller radius before being detected. Lighter particles describe circle of smaller radius before being detected. All particles describe circle of the same radius regardless of their charge and mass. None of the above.
