What is specific charge? Write its standard value.

(N/A) The specific charge of a particle is defined as the ratio of its charge $(q)$ to its mass $(m)$.
Mathematically,it is expressed as: $\text{Specific charge} = \frac{q}{m}$.
The $SI$ unit of specific charge is $\text{C/kg}$.
For an electron,the specific charge is approximately $1.76 \times 10^{11} \ \text{C/kg}$.
