J.J. Thomson's cathode ray tube experiment demonstrated that

Options

  1. Acathode rays are streams of negatively charged ions
  2. Ball the mass of an atom is essentially in the nucleus
  3. Cthe e / m of electrons is much greater than the e / m of protons
  4. Dthe e / m ratio of the cathode ray particles changes when a different gas is placed in the discharged tube

Correct answer

C. the e / m of electrons is much greater than the e / m of protons

Step-by-step solution

According to J.J. Thomson's cathode ray tube experiment, the e / m of electrons is much greater than the e / m of protons.
