Question

Electrons emitted from various sources using different methods:

• A. Have the same e/m values
• B. have different e/m values
• C. e/m value depends on the temperature
• D. has e/m value equal to 1

Answer 1

The correct option is A Have the same e/m values

Electrons emitted from different methods have the same e/m ratio because the charge and the mass of an electron do not depend on the nature of the gas used.
