How does Millikan's experiment link electronic charge to specific charge and electron mass?.
- A.By measuring the total mass of electrons in a sample.
- B.By calculating the specific charge using the charge and mass of the electron.
- C.By observing the behavior of electrons in a magnetic field.
- D.By using thermionic emission to release electrons.
Model answer
What a good answer should say
- By calculating the specific charge using the charge and mass of the electron.
Explanation
Why this works
Millikan's experiment allows for the determination of the charge of the electron, which can then be used to calculate the specific charge (charge-to-mass ratio) of the electron.
