PHY238 SONG #2 Judson University General Physics II (Showing Our kNowledge Growth) March 2, 2022 Physical Constants: Mass of electron: 9.1 x 1031kg Charge of electron: e = 1.6 x 10-19 C Coulombs law constant: k = 9 x 109 Nm3/C2 Permittivity of free space: s. = 8.85 x 10-12 C2 / ( Nm?) Permeability of free space: M. = 47 x 10-7 N / A 5. An electron is shot horizontally out of a cannon aimed due North into a mass spectrometer at a speed of 34,400 m/s. The electron turns in a counter-clockwise horizontal half circle striking the detector plate at a point 28 mm from the point of entry. What is the strength and orientation of the magnetic field
