Question 1 6 pts Three identical capacitors are connected in series to a battery. While the capacitors are still connected, a person then mechanically pulls the plates of two of the capacitors further apart, increasing the plate separation for both of them by a factor of 7.0, while leaving the plate separation for the third capacitor unchanged. As a result of this action, the amount of energy stored in the three capacitors has changed by what percent? Give the magnitude of the answer, regardless of whether it has increased or decreased.
