In a particular Millikan oil-drop apparatus, the plates are 2.25cm apart. The oil used has a density of 0.805g/cm^3, and the atomizer that sprays the oil drops produces drops of diameter 1.00 x 10^-3mm. if another drop of the same oil requires a potential of 64.5v to hold it stationary, how many excess electrons did it contain?
