The specific charge of a proton is 9.6×107 C kg -1the specific charge of and alpha particle will be :

A

9.6×107 C kg-1

B

19.2×107 C kg-1

C

4.8×107 C kg-1

D

2.4×107 C kg-1

Answer

4.8×107 C kg-1

Explanation

Solution

: For proton,

Specific charge =em=9.6×107Ckg1= \frac{e}{m} = 9.6 \times 10^{7}Ckg^{- 1}

For alpha particle

Specific charge

}{= 4.8 \times 10^{7}Ckg^{- 1}}$$
