AP Physics C: Electricity and Magnetism Question of the Day

Charge is distributed uniformly over the area of the two plates of a parallel plate capacitor, resulting in a surface area charge density of on the plates (the top plate is positive and the bottom is negative, as shown below). Each plate has area and are separated by distance . A material of dielectric constant has been placed between the two plates.

Which of the following would not result in an increase in the measure of electric potential difference between the two plates?
