potential across C4
V4 = q4 /c4 = 6/3.6 = 1.67 V
charge through C3
q3 = 13 - 6 = 7 uC
since, C3 and C4 are in parallel so voltage must be same across them
q3/c3 = v4
7 / c3 = 1.67
c3 = 4.2 uF
======
voltage across C1
V1 = V - V2 - V4
V1 = 10.5 - 13 / 2.8 - 1.67
13 / c1 = 4.187
c1 = 3.1 uF
=====
b)
c3 = 4.2 uF
======
Comment before rate in case any doubt, will reply for sure.. goodluck
