        The diagram shows an oil droplet of mass m between two parallel metal plates separated by a distance d. The upper plate is at potential +V and the lower plate is at potential −V. The droplet is stationary.

        Two parallel plates with voltage +V and -V. A point charge -q is between the plates, separated by distance d.

        What is the magnitude of the charge on the droplet?
