did they use F=qE
No, they only knew that it was an integer multiple and they examined the charge on many individual drops to try and determine what number they were a common multiple of.did they know how many electrons were in their oil drops .
Robert Millikan conducted his Oil Drop Experiment by creating a chamber filled with air and using a small hole at the top to introduce oil droplets. He then used a high-voltage source to ionize the air in the chamber, causing the oil droplets to gain or lose electrons and become electrically charged.
The purpose of Robert Millikan's Oil Drop Experiment was to accurately measure the charge of an electron. By observing the motion of the oil droplets in the chamber and manipulating the electric field, he was able to calculate the charge of a single electron.
Robert Millikan's Oil Drop Experiment provided the first accurate measurement of the charge of an electron, which was found to be 1.602 x 10^-19 coulombs. It also confirmed the existence of subatomic particles and helped to further develop the understanding of atomic structure.
Robert Millikan's Oil Drop Experiment had a significant impact on the scientific community by providing strong evidence for the existence of subatomic particles and their properties. It also helped to shape the understanding of atomic structure and laid the foundation for future experiments in the field of physics.
The practical applications of Robert Millikan's Oil Drop Experiment include the development of new technologies such as mass spectrometry, which uses similar principles to accurately measure the masses of atoms and molecules. It also helped to advance the understanding of electricity and magnetism, leading to the development of various electronic devices.
