The Millikan oil drop experiment of 1909 allowed Robert A. Millikan to determine the charge of an electron. In the experiment, an oil drop is suspended between two charged plates by an electric force that is equal the gravitational force acting on the 1.1x10^-14 kg drop. What is the charge on the drop if it remains stationary in an electric field of 1.72x10^5 N/C? (use g=10m/s^
