Lab consisted of: Connect the collector to the ground of the VDG with the provided cable. Place your collector approximately 2cm distance and turn on the VDG. Increase the distance to approximately 4cm, then 6cm, and 7cm. The distances don't have to be accurate. Note that in all cases the VDG is to the right and charge collector to the left of the screen. Part1: Explain how and why the spark frequency is dependent on the distance between the VDG and collector. Part2: What is the role of the charge collector? Would we see sparks if the charge collector was not present? Explain (hint: Acceleration means force and Coulomb force is defined as...) Part3: Explain why the electrostatic discharges produce visible light and sound. Part 4: Imagine you approach a candle flame next to a VDG. Do you expect to see something interesting? Can you additionally verify the VDG's polarity, and if so, why? Part5: Estimate how fast an electron is traveling from one dome to the other when this distance is the maximum this VDG can produce sparks. Consider that the VDG is approximately 1 Mega Volt. Do the results make sense (i.e. can an electron really attain such speed?) Show your work (Hint: conservation of mechanical energy at its best, i.e. charge of electron x potential difference = change in kinetic energy) Part 6: Do you expect higher or dimmer sparks if the VDG was in a low-presure chamber? Explain. How does this relate to the previous question? Part 7: Imagine you try to discharge your VDG inside a tube that is filled with Argon (Ar). What do you think it would happen?
