🤓 Based on our data, we think this question is relevant for Professor Wolfman's class at BC.

We are asked what charge for the electron (in terms of α) is consistent with the data.

The electrical charge on any drop was always a whole number multiple of the charge on an electron.

We can use the equation below to find the charge:

$\overline{)\frac{\mathbf{Charge}\mathbf{}\mathbf{on}\mathbf{}\mathbf{an}\mathbf{}\mathbf{oil}\mathbf{}\mathbf{drop}}{\mathbf{Charge}\mathbf{}\mathbf{on}\mathbf{}\mathbf{an}\mathbf{}\mathbf{electron}}{\mathbf{}}{\mathbf{=}}{\mathbf{}}{\mathbf{whole}}{\mathbf{}}{\mathbf{number}}}$

A student re-creates the Millikan oil drop experiment and tabulates the relative charges of the oil drops in terms of a constant, α.

Drop#1 | α |

Drop#2 | 3/2 α |

Drop#3 | 5/2 α |

Drop#4 | 3α |

What charge for the electron (in terms of α) is consistent with this data?

a) 1/2 α

b) α

c) 3/2 α

d) 2 α
