Question

the ratio of specific charge of an alpha particle to that of proton is

Answer 1

Answer:

Alpha particle is doubly ionised He atom. It carries +2e charge (Twice the charge of proton and mass of alpha particle is (2 Neutrons + 2 Protons) is almost 4 times the mass of proton. So, Specific charge of alpha particle =29

Answer 2

Answer:

Explanation:He+2's specific charge is 2/4  .

(specific charge=charge/mass)

specific charge  of proton=1

s.e of alpha/s.e of proton=1/2
