Which of the following may be an incorrect statement regarding cathode

1.	Which of the following may be an incorrect statement regarding cathode ray discharge tube?(a) Presence of negative charge in cathode rays(b) The magnetic field deflects these rays(c) It needs high voltage(d) Protons are present in cathode raysThe question was posed to me in unit test.My doubt stems from Discovery of Sub-atomic Particles topic in chapter Structure of Atom of Chemistry – Class 11
Answer» The correct answer is (d) Protons are PRESENT in CATHODE rays For explanation: Electric discharge in partially EVACUATED tubes in cathode RAY discharge tube. Cathodes rays are made up of electrons. There is a presence of negative charge in cathode rays, magnetic field deflects these rays. Cathode ray discharge tube needs HIGH voltage.
