Solution

The correct option is D All of the above
In Millikan's experiment, tiny oil droplets move with the terminal velocity (no net force) between two metal electrodes by balancing the gravitational force that acts in the downwards direction with viscous drag and electrostatic force that act in the opposite direction.
This experiment was used to determine the charge on an electron.
