Solution

The correct option is B $80 V o l t$
As both the capacitor are in series the charge flowing through it is same,
$Q_{1} = Q_{2}$
Now if we consider potential across $3 μ F$ capacitor as V then potential across $6 μ F$ capacitor is given as $120 - V$ ,
$(120 - V) 6 μ F = V (3 μ F)$
$720 μ F = V (9 μ C)$
$V = 80 V$
