Question
J.J. Thomson's cathode ray tube experiment demonstrated- that
cathode rays are streams of negatively charged ions
all the mass of an atom is essentially in the nucleus
the e/m of electrons is much greater than the e/m of protons.
the e/m ratio of the cathode ray particles changes when a different gas is placed in the discharged tube
Solution
C.
the e/m of electrons is much greater than the e/m of protons.
According to J.J. Thomson's cathode ray tube experiment, the e/m of electrons is much greater than the e/m of protons.
