A capacitor `C_(1) =1.0 muF` F is charged up to a voltage V=60 V by connecting it to battery B through switch (1) Now `C_(1)` is disconnected from battery and connected to a circuit consisting of two uncharged capaictors `C_(2)=3.0 mu F and C_(3)=6.0 mu F` through switch (2) as shown in the figure The sum of final charges on `C_(2) and c_(3)` is :
