Question

physics:

A parallel plate capacitor contains a positively charged plate on the left, and a negatively charged plate on the right. An electron in between the plates moves to the right. Which statement is true? The electron moves to a region having a lower potential and increases its potential energy. The electron moves to a region having a lower potential and decreases its potential energy. The electron moves to a region having a higher potential and increases its potential energy. The electron moves to a region having a higher potential and decreases its potential energy. The potential does not change, and the electron does not change its potential energy. A parallel-plate capacitor with circular plates of diameter D and distance d between them stores energy U when it is connected across a fixed potential difference. In order to triple the amount of energy stored in this capacitor by changing only the size of its plates, the diameter should be changed to: 9D 3D D D/ D/3
