Just need the answers for A, B, and C. Thanks!!

(Figure 1) In the figure are shown three capacitors with capacitances cl = 7.29 times 10-6F , c2 = 2.82 times 10-6F , and c3 = 4.73 times 10-6F . The capacitor network is connected to an applied potential Vab After the charges on the capacitors have reached their final values, the charge on the second capacitor is 4.01 times 10-5C. What is the charge Q1 on capacitor C1? What is the charge on capacitor C3 ? Express your answer in microcoulombs to three significant figures. What is the applied voltage, Vab? Express your answer in volts to three significant figures.

Explanation / Answer

A) the potential difference across C2 and C1 will be the same.so,

4.01*10^-5/(2.82*10^-6)=q/(7.29*10^-6)

or q=1.03*10^-4 C

b) charge on C3=1.03*10^-4+4.01*10^-5

=1.431*10^-4 C

c) Vab=4.01*10^-5/(2.82*10^-6) + 1.431*10^-4/(4.73*10^-6

=44.47 V
