For the situation is question 1, how many elementary charges (unbalanced electrons or protons) are on the oil droplet? [Note: this is the famous Millikan Oil Drop experiment. Millikan was able to take into account the air friction and buoyant force on the droplet (which we ignore here) and solved for the total charge on the drop. By finding that the charges on many drops were multiples of a single common value, he was able to experimentally find the charge on a single elementary charge for the first time. He won the Nobel Prize for that accomplishment.]
