The highest value of e/m of anode rays has been observed when the discharge tube is filled with Hydrogen because of the less mass compared to others.
Option (c).
Explanation:
- Anode rays are basically positive rays formed by positively charged ions after the removal of electrons.
- Hydrogen has the least mass that is it also has the least number of electrons as well due to which it can easily be made into a positive anion with high E/M after removing some electrons.
- E/m is basically the charge of electron upon the mass of the electron, first explained by Millikan's oil drop experiment.
