1. What are the SI units of the value e/m for an electron? Show using equation 2 in the lab write up the right side of the equation simplifies to these units. You do not need to plug in any numbers, just the SI units and simplify. 2. You will notice that a step is missing between equation 2 in the experimental write up and the previous equation presented. This step equates the high positive potential shown to the electrons (the 150-250V) and the electron's kinetic energy. Write out this equation that equates these two values. (You may assume that the initial kinetic energy of the electrons is very small and can be assumed 0 before the positive potential is shown to them.) 3. Explain why the stream of electrons is pushed into a circular path when the electrons enter the constant magnetic field produced by the Helmholtz coils. (You may use equations to help with explanation) 4. Finally, we are conducting this experiment in the presence of the Earth's magnetic field. If we have the current supplied to the Helmholtz coils set at 2Amps, what is the resultant magnitude of the B-field? Without worrying about direction and only magnitude, how does this value compare to the magnitude of the Earth's surface magnetic field that is approximately 25-65 μT? equation 2 for problem 1 is: Thank you for the help!!! e m 2V B²R² 1.
