An ion enters a mass spectrometer with an initial speed of 5.000× 10* m/s. The ion carries a charge having absolute value 9 = 1.602 x 10-19 C, and the initial velocity of the ion is parallel to the plane of the page, as shown in the figure. Within the mass spectrometer, the uniform magnetic field has a magnitude of 0.4000 T and it is directed out of the page (at right angles to the page). On a photographic plate, the ion leaves a mark at a distance of 34.440 cm from the entrance slit, as shown in the figure below. B uniform 34.440 cm Photographic plate 26.
