Physics Question on Dual nature of radiation and matter
Who evaluated the mass of electron indirectly with help of charge:
A
Thomson
B
Millikan
C
Rutherford
D
Newton
Answer
Millikan
Explanation
Solution
Robert A. Millikan performed the famous oil drop experiment in 1909, which allowed him to determine the charge of the electron. By knowing the charge-to-mass ratio of the electron and the charge (which he determined), he could indirectly calculate the mass of the electron. This experiment played a crucial role in accurately determining the fundamental properties of the electron.
So, the correct option is (B): Millikan
