Question

The increasing order for the values of e/m (charge/mass) is:

• A. e, p, n, \( \alpha \)
• B. n, p, e, \( \alpha \)
• C. n, p, \( \alpha \), e
• D. n, \( \alpha \), p, e

Hint:

The electron has the largest e/m ratio among the fundamental particles.

Answer 1

The Correct Option is D

The values of e/m for different particles (e = electron, p = proton, n = neutron, \( \alpha \) = alpha particle) follow this increasing order: \[ \text{Neutron (n)}<\text{Alpha particle (\( \alpha \))}<\text{Proton (p)}<\text{Electron (e)} \]
