During the oil drop experiment you measure the distance a droplet of oil travels over a given amount of time. You use that to calculate the terminal velocity. From that you find that the droplet has a radius of 7.78 × 10-7 m and a mass of 1.62 × 10-15 kg. Use the first equation below to find the volume and use the second equation to find the total charge (Qtot).
