Professor PC Thomas Classes · Answer

(c) : For proton, \ $ 	ext { specific charge }=\frac{e}{m}=9.6 	imes 10^7 \mathrm{C} \mathrm{~kg}^{-1} $ \  For alpha particle, \ $ 	ext { specific charge }=\frac{2 e}{4 m}=\frac{1}{2} \frac{e}{m}=\frac{1}{2} 	imes 9.6 	imes 10^7 \ =4.8 	imes 10^7 \mathrm{C} \mathrm{~kg}^{-1} $
