Question

A square parallel plate capacitor in a circuit with a 2.0 V battery is replaced with a new one. If the sides of the new plates are 3 × as large as those of the old, and the distance between the plates is 1/4 of the distance between the old plates, then the maximum potential energy that the new capacitor can store in that circuit is _____ the amount of energy that the old capacitor could store in that circuit.
