¬¬¬¬Cathode rays are produced when a stream of electron in an X-ray tube Hits the glass wall of tube Strikes metal target Pass through a strong magnetic field Pass through an electric field Cathode rays are deflected by: An electric field only A magnetic field only Both of the above None of the above Which of the following not deflected by magnetic field Neutrons Electrons Protons positron the ratio of anode rays depends up on gas of discharge tube. the reason is they originate by ionization of gas in tube they originate from anode of the tube Bothe of the above None of the above The incorrect statement about cathode rays is They travel in straight lines toward cathode They produce heating effect They produce x ray They carry negative charge The introduction of neutron into nuclear composition of an atom would lead to change in The number of electrons The chemical nature of atom Its atomic number Its atomic weight The highest value of e/m of anode rays will observed when tube is filled with N2 O2 H2 He Which of the following properties of atom could be explained correctly by Thomson model of atom Overall neutrality of atom Spectra of hydrogen atom Position of electron proton Stability of atom, This particle was discovered by bombarding of alpha particle over beryllium 0n1 e p None of these The increasing order of the value of e/m of electron proton and neutron- e
