Answer» Solution :Specific charge of an electron `=(1.6xx10^-19)/(9.1xx10^-31) " COULOMB//kg"` `=0.176xx10^12=17.6xx10^10 " coulomb /kg"` Specific charge of a proton `=(1.6xx10^(-19))/(1.67xx10^(-27))"coulomb /kg" = 0.96xx10^8 "coulomb/kg"` Specific charge of `alpha`-particle `=(2xx1.6xx10^(-19))/(2XX10^(-27)(1.67+1.72))=(1-6xx10^8)/(3.39)=0.472xx10^8 "coulomb/kg"` Hence, ASCENDING order of specific charges of electron, proton and `alpha`-particles is `alpha-"particle" lt "proton" lt "electron"`. |
