Explanation / Answer
here,
C1 = C , C2 = 3 C
C3 = 5 C
C1 and C2 are in parallel, their equivalent capacitance , C4 = C + 3 C = 4 C
C4 and C3 are in series, their equivalent capacitance , Ceq = C4 * C3 /( C4 + C3)
Ceq = 4 * 5 /( 4 + 5) C
Ceq = 20/9 * C
a)
the charge on the other plate is - q ( - 6 mC)
b)
Ceq * V = q
C = 9 * V/ (20 * q)
c)
20/9 * C * 11 = 0.006
solving for C
C = 825 F
