Suppose the electric field between the plates P and P' in Fig is 1.88 X 104 V/m and the magnetic field in both regions is 0.701 T. If the source contains the three isotopes of krypton, 82 Kr, 84 Kr, and 86Kr, and the ions are singly charged, find the distance between the lines formed by the three isotopes on the photographic plate. Assume the atomic masses of the isotopes (in atomic mass units) are equal to their mass numbers, 82, 84, and 86. (One atomic mass unit = 1 u = 1.66 X 10- 27 kg.)
