In the Millikan oil drop experiment, the charge of an electron is measured by placing an ionized oil drop of mass, \( m \), and net charge, \( e \), between the conducting plates of a parallel plate capacitor that produces a vertically downward electric field as shown in the diagram below. If the electron is in static equilibrium between the plates, which of the following is the correct expression for the electron charge of magnitude \( e \)? The voltage difference between the capacitor plates is \( V \) and the distance between the plates is \( d \).

The diagram depicts:

- Two parallel plates: The top plate is positively charged, and the bottom plate is negatively charged.
- An electron is placed between these plates.
- The distance between the plates is \( d \), shown by a vertical arrow labeled \( d \).

The options for the expression are:

- a. \( V/(mgd) \)
- b. \( mgV/d \)
- c. \( d/(mgV) \)
- d. \( Vd/mg \)
- e. \( mgd/V \)
