The specific charge of a proton is 9.6107c/kg. The specific charge of an alpha particle will be:
Answers
Answer:
An alpha particle is the nucleus of a He-4 atom and has two protons and two neutrons. Since only protons carry charge, the charge of an alpha particle will be twice the charge of a single proton.
Charge on a single proton: +1.602x10^-19C
Mass of proton: 1.67x10^-27 kg
Net charge on a kilogram of protons:
+1.602x10^-19C / 1.67x10^-27 kg = 9.58x10^7 C/kg
Since an alpha particle has two protons, then the charge on the alpha is twice the charge on a proton. The mass of an alpha particle is essentially 4 times the mass of proton since the masses of protons and neutrons are very similar (p==1.0073 amu, n==1.0087 amu)
Net charge on one kilogram of alpha particles:
2(+1.602x10^-19C) / 4(1.67x10^-27 kg) = 4.79x10^7 C/kg
Answer:
4.8*10*7c/kg
