In the circuit in (Figure 1), switch 1 has been in position a and switch 2 has been closed for a long time. At $t=0$, switch 1 moves instantaneously to position b.Eight hundred microseconds later, switch 2 opens, remains open for $300?\mathrm{s}$, and then recloses. Suppose that $C=300\mathrm{nF}$. Figure 1 of 1 What percentage of the initial energy stored in the capacitor is dissipated in the $3\mathrm{k}?$ resistor? Express your answer as a percentage using three significant figures.
