An electron (m = 9.11x10 31 kg) with 5.37x10-16 J of kinetic energy is circling horizontally inside of a uniform, vertical magnetic field. The radius of the electron's path is 0.824 m. a) What is the electron's speed? [m/s] b) What is the magnitude of the magnetic field vector? [T] c) What is the frequency of the electron's circular motion? [Hz] What is the period of the electron's circular motion? [s] e) Sketch the electron and its path using the "top" point of view (as seen from above). Include (and label) the v, B, and F vectors
