How did J.J. Thomson measures the ratio of charge to mass (e/me) of the electron?

Options

  1. ABy using X-ray diffraction
  2. BBy using a Geiger counter
  3. CBy using a cathode ray tube and applying electrical and magnetic fields
  4. DBy using a spectrometer

Correct answer

C. By using a cathode ray tube and applying electrical and magnetic fields

Step-by-step solution

J.J. Thomson measured the ratio of charge to mass (e/me) of the electron using a cathode ray tube and applying electrical and magnetic fields perpendicular to each other and to the path of electrons.
