A) electric charge depends on velocity
B) specific charge of electron is\[1.76\times {{10}^{11}}\] \[Ck{{g}^{-1}}\]
C) electron has wave nature
D) electric charge is quantized
E) electron has particle nature
Correct Answer: D
Solution :
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 integral multiple of an elementary charge\[1.602\times {{10}^{-19}}C\]. This proved that charge is quantized.
