see juana i am not sure.but i think that whencapacitors are connected again then they must be possessing some potential difference and charges indivisually.so hence when they are connected pottential diff. across them will be=highest pot. diff. of 1 capacitor - lowest pot diff of other  capacitor.charge can be found depending on combinations.

my tuition teacher did diff.,continuity,derivatives,inverse trig. ratiosand some app. together.i am not clear with any of the conceptsnow as it was done very high pace. what do i do?
