Question:
Arrange the following particles in increasing order of values of \( e/m \) ratio: electron (e), proton (p), neutron (n) and \( \alpha \)-particle (\( \alpha \)):
Arrange the following particles in increasing order of values of \( e/m \) ratio: electron (e), proton (p), neutron (n) and \( \alpha \)-particle (\( \alpha \)):
Show Hint
The \( e/m \) ratio is highest for the electron and lowest for the \( \alpha \)-particle.

- \( n, p, e, \alpha \)
- \( p, e, n, \alpha \)
- \( e, p, n, \alpha \)
- \( e, p, \alpha, n \)
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
The ratio \( e/m \) for the electron is the highest, followed by the proton, neutron, and finally the \( \alpha \)-particle (which has a higher mass). Therefore, the increasing order is \( e, p, n, \alpha \).
Final Answer: \[ \boxed{e, p, n, \alpha} \]
Final Answer: \[ \boxed{e, p, n, \alpha} \]
