Statement of a problem № 41877


Suppose the electric field between the electric plates in the mass spectrometer of Fig. 20-39 is 2.48 X 104 V/m and the magnetic field B = B’ = 0.68 T. The source contains carbon isotopes of mass numbers 12, 13, and 14 from a long-dead piece of a tree (To estimate atomic masses, multiply by 1.67 X 10-27Kg) how par apart are the lines formed by the singly charged ions of each type on the photographic film? What if the ions were doubly charged?
