Vedclass · Answer

(A) Specific charge is defined as the ratio of charge $(q)$ to mass $(m)$,i.e.,$\frac{q}{m}$.For a proton $(p)$: Charge $=  1e$,Mass $= 1 	ext{ amu}$. Specific charge $= \frac{1e}{1} = 1e$.For an $\alpha$-particle $(\alpha)$: Charge $=  2e$,Mass $= 4 	ext{ amu}$. Specific charge $= \frac{2e}{4} = 0.5e$.The ratio of specific charge of a proton to an $\alpha$-particle is $\frac{1e}{0.5e} = \frac{2}{1}$,which is $2:1$.

The ratio of specific charge of a proton and an $\alpha$-particle is
