Three capacitors of capacitances 1 muF, ...

Three capacitors of capacitances `1 muF, 2 muF`, and `2 muF`, are cahrged up to the potential difference `30 V, 10 V`, and `15 V`, respectivly. If terminal `A` is connected with `D C` is connected with E and F is connected eith B, the find the charge flow in the ciruit and the final charge on the capacitors.
.

Let charge flow is q.
Now appliying Kirchhoffs voltage low
` -( q-20 )/( 2) -( ( 30+q))/( 2) +( 30 -q)/( 1) =0 `

` -2q =-25`
` q= 12 . 4 mu C `
Final charges plates
