1/6 is what i got

There's no closed circuit at all....there won't be any current flow right?

S 2 is closed

Yeah still

Circuit is broken at fully filled capacitors

yes but the potentials across the C2 30 ohm and 10V should be same as the potential across C1 and 70ohm right

Ah right

wdym both circuits are closed 5/30 1/6 shouldnt it be the ans since all capacitor will be in steady state

What how After the switch is closed the charged capacitors will behave like batteries and the uncharged one becomes short circuited

only 1 capacitor not in steady state we will only take 30 ohm in to acc no? what look first S1 is closed for long time so all C in steady state wait a sec nvm idk what why?

Potential diff across the same points is the same Same logic used in parallel circuits

oh u taking them as a whole ic where did 130 and 4 come from in right most wire

100 and 30 are in series and then the capacitors were giving emf in the opposite direction of the battery so 5-0.5-0.5

ah ic still wont they be in steady state so no current passes through? if u say they will discharge , can they even discharge when battery there?

When you close the switch S1 why is the current flowing werent they in steady state before.When the system changes the steady state will be disturbed and it will want to go towards another steady state Yes
