What is the ratio of specific charge (e/m) of an electron to that of a hydrogen ion?

Answer:

Specific charge of electron (\[{{S}_{1}}\]) \[=1.76\times {{10}^{8}}C/g\] Specific charge of hydrogen (\[{{S}_{2}}\]) \[=9.58\times {{10}^{4}}C/g\] \[\therefore \]\[\frac{{{S}_{1}}}{{{S}_{2}}}=\frac{1.76\times {{10}^{8}}}{9.58\times {{10}^{4}}}=\frac{1837}{1}\] Therefore, the ratio of specific charge (e/m) of an electron to that of a hydrogen ion is 1837: 1.
