Answer #1

C1 and C2 are in parallel, so their equivalent will be 6+3 = 9uF

C3 in series, so equivalent capacitance = 9x18/(9+18) = 6uF

Total charge flowing through the battery = 30 x 6 = 180 uC

This charge will be divided between c1 and C2 in the ratio of capacitance, so q1 = 2q2 and q1+q3 = 180

So, q2 =180/3= 60 uC

Hence 60 uC will be the answer
