When capacitors are connected in series, they have the same charge. The equivalent capacitance (C_eq) for capacitors in series is given by 1/C_eq = 1/C1 + 1/C2. For the given capacitors, C_eq = 2/3 μF. The charge (Q) is given by Q = C_eq * V, where V is the voltage. So, Q = (2/3 μF) * 1200 V = 0.80 mC.
