Question

The ratio of specific charge of an electron to that of a proton is

Answer 1

e/m of electron=1.758*10" e/m of proton= 9.57*10 power 7 their ratio is 1836.therefore mass of proton is 1836 times mass of electron

Answer 2

Answer: $0.18\times 10^{4}$

Explanation: Specific charge is the ratio of the charge of a subartomic particle to it's mass.

Specific charge=$\frac{e}{m}$

where e = charge

m = mass

Specific charge of electron=$\frac{e}{m}=\frac{1.6\times 10^{-19}C}{9.1\times 10^{-31}kg}=1.76\times 10^{11}C/kg$

Specific charge of proton=$\frac{e}{m}=\frac{1.6\times 10^{-19}C}{1.67\times 10^{-27}kg}=9.6\times 10^{7}C/kg$

Ratio of Specific charge of electron to Specific charge of proton=$\frac{1.76\times 10^{11}C/kg}{9.6\times 10^7C/kg}=0.18\times 10^{4}$
