Detailed Solution

Initial situation after the reconnection is shown in figure (a) and the final situation in figure (b). The charge transferred by C1is q0−q1and the capacitors C2 and C3 are in series, so q2=q3. Other way to solve the questions is to equalize the potentials across C1 and series combination of C2 and C3
