Consider the following statements, which of the following is/are true? i) Charge to mass ratio of canal rays are found to depend on the gas from which these originate ii) Cathode rays produce fluorescence and phosphorescence when it hit on the corresponding materials iii) J.J. Thomson's model of an atom could clearly explain "atom is electrically neutral" iv) Behaviour of canal rays in the electrical or magnetic field is opposite to that observed for cathode rays v) Charge to mass ratio of cathode rays are found to depend on the gas from which these originate
