Web7 de ago. de 2024 · J. J. Thomson measured the charge to mass ratio of electron in year 1897, and R. K. Millikan measured charge of electron in year nearly about 1910, i.e., Thomson knew only the charge to mass ratio of electron in 1903. Then how did he was able to determine the momentum of electron when he didn't knew the mass of electron? WebThomson determined that charged particles much lighter than atoms, particles that we now call electrons made up cathode rays. Cathode rays are formed when electrons emitted from one electrode and travel to another when a voltage is applied in a vacuum.
