Across which one?
q = V1C1
V2 = q/C2
Find C1 and C2 first.
An air condenser has an area of 100 cm^2 the plates being 4mm apart. It is connected in series with another condenser having plate area of 20cm^2 plates being separated by dielectric 0.1mm thick with E=2.5. If the potential difference across an condenser is 1000volts; find the potential difference across the combination.
