For my electronics work I have a question to answer:

"A 1000V source is used to fully charge a 1μF capacitor. The capacitor is then disconnected from the source and connected to two additional capacitors (2μF and 8μF) as shown in the circuit schematic below.

a) Calculate the final voltage across the 1μF capacitor after connecting it to the two capcitors.
b) Calculate the variation of energy associated with this process."

For the first part am I supposed to act as if the three capacitors are in parallel or what? And for the second bit what is the variation of energy? Any help would be greatly appreciated.
