In a particular Millikan oil-drop apparatus, the plates are2.25 cm apart. The oil used has a density of0.815 g/cm3 , and the atomizer that sprays the oil dropsproduces drops of diameter1.00×10−3 mm.
A) What strength of electric field isneeded to hold such a drop stationary against gravity if the dropcontains five extra electrons?
B) What should be the potential differenceacross the plates to produce this electric field?
C) If another drop of the same oilrequires a plate potential of 65.3 V to hold itstationary, how many excess electrons did it contain?
