You have a summer job working in a research laboratory. Your task is to obtain a measurement of the charge on an electron using the famous Millikan oil drop experiment. In the design, oil drops produced by a sprayer are to be suspended in between the electrode plates. For that, the oil drops have to be charged to -1 e, where e is the charge of an electron and a uniform electric field has to be applied between the electrodes in such a way that the electric force on a given drop balances gravitational force on it. The electrode plates in your design are separated by 2.5 cm dry air medium. You know that the dry air supports upto a maximum electric field strength that corresponds to an electric potential of 75 kV. You are given an oil of density 920 kg/m³ and the sprayer produces oil drops of 1.00 um in radius. Will your design work? Justify your answer. The charge of the electron is 1.6x 10-19C.
