An increasing order (lowest first) for the values of e/m for electron (e), proton (p), neutron (n) and alpha (α) particle is:

View answer and explanation

Correct option: B

n,α,p,e

Option B (n,α,p,e) is correct because the e/m ratio increases in the order: neutron (0), alpha, proton, and electron due to their respective charges and masses.
