Picture shown three capacitors with capacitances C1=6.00μF,C2=3.00μF,C3=5.00μF . The capacitor network is connected to an applied potential Vab. After the charges on the capacitors have reached their final values, the charge Q2 on the second capacitor is 40.0 μC. Part A What is the charge Q1 on capacitor C1?   Part B What is the charge on capacitor C3? Express your answer in microcoulombs to three significant figures.   Part C What is the applied voltage, Vab? Express your answer in volts to three significant figures.
