Vedclass · Answer

(A) The specific charge is defined as the ratio of charge to mass $(q/m)$.For an electron: $q_e = e$,$m_e \approx 9.1 	imes 10^{-31} \ kg$.For a proton: $q_p = e$,$m_p \approx 1.67 	imes 10^{-27} \ kg$.For an $\alpha$-particle: $q_{\alpha} = 2e$,$m_{\alpha} \approx 4 	imes 1.67 	imes 10^{-27} \ kg$.Calculating the ratios:$(q/m)_e = e / m_e$$(q/m)_p = e / m_p$$(q/m)_{\alpha} = 2e / (4m_p) = 0.5 (e / m_p)$Since $m_e \ll m_p$,the ratio for the electron is the largest.Comparing proton and $\alpha$-particle: $(q/m)_p > (q/m)_{\alpha}$.Therefore,the order is $(q/m)_e > (q/m)_p > (q/m)_{\alpha}$.

The order of the $q/m$ ratio for a proton,$\alpha$-particle,and electron is:
