Q. 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.
Q. Two narrow slits 41 µm apart are illuminated with light of wavelength 604 nm. What is the angle of the m=3 bright fringe in degrees?
