Suppose the electric field between the electric plates in the mass spectrometer of Fig. 20−38 is 2.04×104 V/m and the magnetic fields B = B′ = 0.40 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 1.67×10−27 kg. ) Figure 20−38 (a) How far apart are the lines formed by the singly charged ions of each type on the photographic film? mm (b) What if the ions were doubly charged? mm

The figure below shows a schematic diagram of a mass spectrometer. A charged particle enters a velocity selector, in which a uniform electric field E (created by charged plates) points to the right, and a magnetic field Bin points into the page. Upon exiting the velocity selector, the particle enters a deflection chamber with a magnetic field B→0,in. The particle travels a semicircular path until it hits a photographic plate at point P: Assume the particle is a singly charged ion with mass m = 2.12×10−26 kg. The magnitude of the electric field is 970 V/m, and the magnitude of both the magnetic field in the velocity selector and in the deflection chamber is 0.900 T. What is the radius r (in m) of the particle's path in the deflection chamber? m

The figure below shows the schematic for a mass spectrometer which consists of a velocity selector and a deflection chamber. The magnitude of the magnetic field in both the velocity selector and the deflection chamber is 0.0110 T, and the electric field between the plates of the velocity selector is 1600 V/m. If a singly charged ion with a mass of 6.70×10−27 kg travels through the velocity selector and into the deflection chamber, determine the radius of its trajectory in the deflection chamber. m

Consider the mass spectrometer shown schematically in the figure below. The magnitude of the electric field between the plates of the velocity selector is 2.70×10 3 V/m, and the magnetic field in both the velocity selector and the deflection chamber has a magnitude of 0.0400 T. Calculate the radius of the path for a singly charged ion having a mass m = 2.32×10−26 kg.
