(II) Suppose the electric field between the electric plates in the mass spectrometer of Fig. 20–41 is \(2.88 \times 10^{4} \mathrm{~V} / \mathrm{m}\) and the magnetic fields are \(B=B^{\prime}=0.68 T\). The source contains carbon isotopes of mass numbers 12, 13, and 14 from a long-dead piece of a tree. (To estimate masses of the atoms, multiply by \(1.67 \times 10^{-27} \mathrm{~kg}\).) How far apart are the lines formed by the singly charged ions of each type on the photographic film? What if the ions were doubly charged?
