All of the above

Vedclass · Answer

(D) According to the quantization of electric charge,the total charge $q$ on any body is always an integral multiple of the elementary charge $e$,where $e = 1.6 	imes 10^{-19} \ C$.The formula is $q = n 	imes e$,where $n$ is an integer $(n = 1, 2, 3, \dots)$.To check if a charge is possible,we calculate $n = q / e$:For option $A$: $n = (4.0 	imes 10^{-19}) / (1.6 	imes 10^{-19}) = 2.5$ (Not an integer).For option $B$: $n = (6.0 	imes 10^{-19}) / (1.6 	imes 10^{-19}) = 3.75$ (Not an integer).For option $C$: $n = (10.0 	imes 10^{-19}) / (1.6 	imes 10^{-19}) = 6.25$ (Not an integer).Since $n$ is not an integer for any of the given options,none of these charges are possible in Millikan's oil drop experiment. Therefore,the correct answer is $D$.

Which of the following charges is $NOT$ possible in Millikan's oil drop experiment?
