Which of the following pairs has the identical \(e / m\) value?
- A An \(\alpha_{-}\)-particle and deuterium ion
- B A proton and neutron
- C An electron and \(y\)-rays
- D A proton and deuterium ion
Answer & Solution
Correct Answer
(A) An \(\alpha_{-}\)-particle and deuterium ion
Step-by-step Solution
Detailed explanation
Deuterium and \(\alpha\)-particles have identical value of \(e / m\). Both deuterium and \(\alpha\)-particles emit and absorb at the equal frequencies.
