An oil drop (density = 0.80 grams/cm3) has a diameter of 2.30 ?m. (This is about the size of a bacterium.) (A) Find the mass of the drop.: Suppose this drop has 3 excess electrons: it is slightly negative in total charge. It is in the presence of an electric field which points straight down, and the electric force on the drop is just strong enough to balance the weight of the drop, so it does not move. What is the value of the electric field?
