MCQ
The $(e/m)$ for positive rays in comparison to cathode rays is
  • ✓
    Very low
  • B
    Very high
  • C
    Same
  • D
    None
✓

Answer

Correct option: A.
Very low
a
Cathode rays contains electrons and positive rays contain positive charged gaseous atom mass of electron is negligible in comparison to positive charge atom
