The Attempt at a Solution
Apologies for the question image not being very clear . I will refer capacitors by numerical value of their capacitance .
The 6 , 4 , 8 capacitors are in parallel .
9 , 9 , 7 are shorted out .So , we can remove them from the circuit .
So , effectively , the equivalent of 6,4,8 is in series with the 36 capacitor .
One end of 6,4,8 is at 40 Volts .Other end I calculated to be at 40/3 volts.
From this I get potential difference across 8μf capacitor to be 80/3 volts and charge 640/3 μC .
I get Option 3) .
Is this correct ?
