What is definition of specific charge of an electron?

Specific charge is the ratio of an electron’s electric charge to its mass.

Charge on electron(e)=1.67*10^–19 coulomb

Mass of electron(m)=9.1*10^–31 kg

By defination,

Specific charge on an electron

e/m

1.67*10^–19/9.1*10^–31

1.7*10^11 coulomb/kg
