Millikan's oil -drop experiment established that

Options

A. A)electric charge depends on velocity
B. B)specific charge of electron is `1.76xx10^(11)Ckg^(-1)`
C. C)electric has wave nature
D. D)electric charge is quantized

Answer

D

Explanation

Millikan performed the pioneering oil drop experiment for the precise measurement of the charge on the electron .He found that the charge on an oil droplet was always an intergral multiple of an elementary charge `1.602xx10^(-19)C`. This proved that charge is quantized .
