Two capacitors of unknown capacitance...

Two capacitors of unknown capacitance `C_(1) and C_(2)` are connected first in series and then in parallel, across a battery of 100V. If the energy stored in the two combinations is 0.045 J and 0.25 J respectively determine the values of `C_(1) and C_(2)`. Also calculate the charge on each capacitor in parallel combination.
