Suppose the electric field between the electric plates in themass spectrometer of Figure 27-33 in the textbook is 2.64Ã—104 V/mand the magnetic fields are B=Bâ€²=0.36T. The source contains carbonisotopes of mass numbers 12, 13, and 14 from a long dead piece of atree. (To estimate atomic masses, multiply by 1.66Ã—10âˆ’27kg.)
How far apart are the lines formed by the singly charged ions ofeach type on the photographic film?
What if the ions were doubly charged?
