The specific charge of a proton is 9.6xx...

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

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)`

Text Solution

Verified by Experts

The correct Answer is:
C
(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)`
