Millikan Oil Drop Experiment JS Documents
Slavomir Tuleja, Wolfgang Christian, Mario Belloni, and Anne Cox
The Millikan Oil Drop Exploration is a virtual version of the Millikan's experiment. The experiment is based on balancing forces: the gravitational pull down on an oil drop and the electric force up on ionized particles. The simulation includes a schematic of the apparatus and simulated microscope viewing the oil drops. The oil drops fall and enter the a region where they can be seen through the microscope. Turning on an applied voltage provides a force that can, if adjusted correctly, exactly balance the gravitational force on the drop.
