An RC-circuit , with `R=600kOmega` and `C=10muF` , is connected to a 5.0-V battery until the capacitor is fully charged . Then , the battery is suddenly replaced with a new 3.0-V battery of opposite polarity . At what time (in seconds) after this replacement will the energy stored in the capacitor be zero ? (given that `e~~8/3`)
