Two capacitors of unknown capacitances ${ C }*{ 1 }$ and
${ C }*{ 2}$ are connected first in series and then in parallel across a battery of 100 V.

If the energy stored in the two combinations is 0.045 J and 0.25 J respectively, then determine the value of ${ C }

*{ 1 }$*

and ${ C }{ 2}$ Also, calculate the charge on each capacitor in parallel combination.

and ${ C }
