Two identical parallel-plate capacitors, each with capacitance 15.5 µF, are charged to potential difference 49.5 Vv and then disconnected from the battery. They are then connected to each other in parallel with plates of like sign connected. Finally, the plate separation in one of the capacitors is doubled. (a) Find the total energy of the system of two capacitors before the plate separation is doubled. .0367 Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. J (b) Find the potential difference across each capacitor after the plate separation is doubled. (c) Find the total energy of the system after the plate separation is doubled. (d) Reconcile the difference in the answers to parts (a) and (c) with the law of conservation of energy. O Positive work is done by the agent pulling the plates apart. O Negative work is done by the agent pulling the plates apart. No work is done by pulling the agent pulling the plates apart.
