Millikan`s oil drop experiment attempts to measure the charge on a single electron,e,by measuring the charge of tiny oil drops suspended in an electrostatic field.It is assumed that the charge on the oil drop is due to just a small number of excess electrons. The charges 3.90×10^-19C, 6.50×10^-19C and 9.1×10^-19C are measured on three drops of oil. The charge of an electron is deduced to be,
