Imagine that you are measuring the mass of a particle in a mass spectrometer. The magnitude of the electric field between the plates of velocity selector is 3300000 V/m, the magnetic field is 1.5 T everywhere. The charge of the particle is equal to the charge of the electron (1.6e-19 C). The measured radius of trajectory in the spectrometer is 1.1 mm. The velocity of this particle as it passes through the velocity selector is v= m/s. The mass of this particle is m= kg.
