\frac{e}{m}

value for electron is the ratio of charge on an electron to its mass.
Charge on an electron

= 1.602 \times 10^{- 19} C .

Mass of an electron

= 9.109 \times 10^{- 31} K g .

Hence,

\frac{e}{m} = \frac{1.602 \times 10^{- 19} C}{9.109 \times 10^{- 31} K g}

\Rightarrow \frac{e}{m} = \frac{1.602 \times 10^{- 19} C}{9.109 \times 10^{- 31} K g}

\Rightarrow \frac{e}{m} = 1.76 \times 10^{11} C / k g
