The electric field between the plates of a gear selector in a mass spectrometer is 1×105 V/m. The magnetic field of the speed selector is the same as that of the spectrometer. A beam of +e charged neon ions leaving the speed selector moves in a circular path in the spectrometer before hitting the photographic plate. After a certain time, three spots are observed at distances of 7.4 cm, 7.8 cm and 8.15 cm, respectively.Find the magnetic field assuming that the difference in mass between two isotopes is 1 amu (atomic mass unit):Select the correct answer:
