The specific charge of a proton is `9.6xx10^(7)"C kg"^(-1)`.
The specific charge of an alpha particle will be

Options

A. `9.6xx10^(7)"C kg"^(-1)`
B. `19.2xx10^(7)"C kg"^(-1)`
C. `4.8xx10^(7)"C kg"^(-1)`
D. `2.4xx10^(7)"C kg"^(-1)`

Answer

C

Explanation

(c ) : For proton,
Specific charge `=(e)/(m)=9.6xx10^(7)"C kg"^(-1)` For alpha particle,
Specific charge `=(2e)/(4m)=(1)/(2)(e)/(m)=(1)/(2)xx9.6xx10^(7)`
`=4.8xx10^(7)"C kg"^(-1)`
