The e/m value for the canal rays is maximum for:
Correct answer: A. Hydrogen
- A. Hydrogen
- B. Nitrogen
- C. Helium
- D. Argon
Explanation
e/m is largest for the particle with the smallest mass and single positive charge. Hydrogen ion is the lightest, so it has the highest e/m. Heavier ions like nitrogen, helium, and argon have smaller e/m values
