Question

Suppose the electric field between the electric plates in the mass spectrometer of (Figure 1) is 3.18×104V/m3.18×104V/m and the magnetic fields B=B′=0.77TB=B′=0.77T. 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 ×10−27kg×10−27kg.)

How far apart are the lines formed by the singly charged ions of mass numbers 12 and 13 on the photographic film?

How far apart are the lines formed by the singly charged ions of mass numbers 13 and 14 on the photographic film?

What if the ions were doubly charged?
