(C) Initial capacitance $C_1 = 0.2 \, \mu F$ and initial potential $V_1 = 600 \, V$.Initial charge on the capacitor $Q = C_1 V_1 = 0.2 \, \mu F \times 600 \, V = 120 \, \mu C$.When this capacitor is connected in parallel to an uncharged capacitor $C_2 = 1.0 \, \mu F$,the total charge $Q$ remains conserved.The equivalent capacitance of the parallel combination is $C_{eq} = C_1 + C_2 = 0.2 \, \mu F + 1.0 \, \mu F = 1.2 \, \mu F$.The final potential $V_f$ is given by $V_f = \frac{Q}{C_{eq}}$.$V_f = \frac{120 \, \mu C}{1.2 \, \mu F} = 100 \, V$.
