Consider the mass spectrometer shown schematically in Fig. 1. 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 the velocity selector has a magnitude of 3.50 × 10^2 mT. If the radius of the path for a singly charged ion is 25.6 cm, what is the mass & velocity of the particle as it enters the deflection chamber that, due to design constraints, is under a magnetic field that is twice the field in the velocity selector?
