Silicon wafers are made to create the most groundbreaking invention of mankind - microprocessors. If two silicon wafers (assume dipoles), both with masses of 125grams, radii of 10cm and thickness of 7 um are placed close to each other, separated by a distance of 3cm, what is the electric field strength experienced by an electron placed on the surface of the negatively charged wafer? What is the final velocity of the electron upon reaching the positively charged plate? How much power is generated by the electron in its travel?
