In a mass spectrometer, a doubly charged ion having a particular
velocity is selected by using a magnetic filed of 60 mT
perpendicular to an electric field of 4.2 kV/m. The same
magnetic field is used to deflect the ion in a circular path with a
radius of 85 mm. What is the mass of the ion?
The mass( in kg), m =
