Three capacitors C_1,C_2,andC_3 of capacitance 1muF, 2muF, and 3muF, respectively, are charged separately as shown in the figure. Now these charged capacitors are connected to a battery of epsilon = 20 V and an uncharged capacitor of C = 2muF as shown in figure. , The charge oncapacitor marked C is |

Answer» `3.75 muC`  The circuit can be redrawn as Conserving CHARGES on LOWER plates, we get `-[(x+20)1+(x+2)2+(x+20)3+2x]=-60` or `x=-(15)/(2)V` `|Q_(1muF)|=12.5muC` `|Q_(2muF)|=25muC` `|Q_(3muF)|=37.5muC` `|Q_(2muF)|=15muC` |
