In the circuit shown in the figure,all the capacitors are air-filled.With the switch S open,the 40.0-µF capacitor has an initial charge of 5.00 µC while the other three capacitors are uncharged.The switch is then closed and left closed for a long time.Calculate the initial and final values of the total electrical energy stored in these four capacitors. 
Definitions:
Economic Efficiency
An economic state where every resource is optimally allocated to serve each individual or entity in the best way while minimizing waste and inefficiency.
Deadweight Losses
Losses in total surplus that occur when a market is not in competitive equilibrium, often due to taxes or subsidies.
Economic Efficiency
A situation where all resources are allocated in a way that maximizes the total benefit to society or minimizes waste.
External Cost
A cost that a transaction or activity imposes on a party who is not involved in the transaction, often not reflected in market prices.
