A parallel-plate capacitor is charged to a potential difference of 120V. The area on each plate is 120cm^2 and the spacing between plate is 0.5mm. Find the electric field between the two plates.
An empty parallel plate capacitor is connected between the terminals of a 8.92-V battery and charges up. The capacitor is then disconnected from the battery, and the spacing between the capacitor plates is doubled. As a result of this change, what
