Dual Nature Of Light Question 43
Question: From the following, what charges can be present on oil drops in Millikan’s experiment [MP PET 1995]
Options:
A) Zero, equal to the magnitude of charge on $ \alpha - $ particle
B) $ 2e,\ 1.6\times {{10}^{-18}}C, $
C) $ 1.6\times {{10}^{-19}}C,\ 2.5e $
D) $ 1.5e,\ e $ (Here e is the electronic charge)
Show Answer
Answer:
Correct Answer: B
Solution:
In Millikan?s experiment, the charges present on the oil drops are the integral multiples, so 2e and $ 10e(1.6\times {{10}^{-18}}C) $ charges are present.
