Question

specific charge of proton is 9.6*10⁷ C.kg^-1 find the specific charge of alpha-particle in C.kg^-1

Answer 1

Alpha particle is written as ⁴₂He^2+.
Number of protons = 2
Given the specific charge on proton is 9.6 x 10⁷ C kg^-1
Specific charge on alpha particle would be : 2 x 9.6 x 10⁷ C kg^-1 = 1.92 x 10⁸ C kg^-1
