The specific charges of two particles \( \mathrm{A} \) and \( \mathrm{B} \) are in
P the ratio \( 2: 3 \). If the mass ratio \( \mathrm{m}_{\mathrm{A}}: \mathrm{m}_{\mathrm{B}} \) is \( 2: 3 \), then

W the ratio of their charges \( \mathrm{e}_{\mathrm{A}}: \mathrm{e}_{\mathrm{B}} \), is
(A) \( 1: 1 \)
(B) \( 4: 9 \)
(C) \( 9: 4 \)
(D) \( 2: 3 \)
