A potential difference of 300 V is applied to a series connection of two capacitors of capacitances C1=2.00 microfarad and C2=8.00 microfarad. Suppose that the charged capacitors are then disconnected from each other and from the battery. They are then reconnected with plates ofoppositesigns wired together. What now are (a) q1, (b) V1, (c) q1, and (d) V1?
