If an unchanged parallel-plate capacitor (capacitance C) is connected to a battery, one plate becomes negatively charged as electrons move to the plate face (area A). In Figure the depth d from which the electrons come in the plate in a particular capacitor is plotted against a range of values for the potential difference V of the battery. The vertical scale is set by d = 1.00 pm, and the horizontal scale is set by Vs = 20.0V. What is the ratio C/A?
