Question

The ratio of the specific charge (e/m) of a proton to that of an alpha particle is
a) 1:2
b) 1 : 1/4
c) 1:4
d) 1 : 1/2​

Answer 1

Answer:

1:2 is your answer

Explanation:

Alpha particle is a helium nucleus that comprises two protons and two neutrons, and the charge is twice the charge of the proton while the mass is around four times greater. Mass of helium = 4m. Therefore, the charge to mass ratio of an alpha particle is approximate twice the charge to mass ratio of a proton.
