Exercise 87

Consider the mass spectrometer shown schematically in Figure P19.36. The electric field between the plates of the velocity selector is 950 V/m, and the magnetic fields in both the velocity selector and the deflection chamber have magnitudes of 0.930 T. Calculate the radius of the path in the system for a singly charged ion with mass m = 2.18 × 10 26 kg. Hint: See Problem 35.
