When the steady state is reached by keeping switch in position-1 then swich 'S' is transferred from position 1 to 2. Then

Answer»

Charge on `3F` capacitor is `30C` after `S` is transferred from positiojn 1 to 2
Charge on `3C` capacitoris `650/16C` after `S` is transferred from POSITION 1 to 2
Work done by the battery is 380 JOULE after `S` is transferred from position 1 and 2
Work done by the battery is 80 Joule after `S` is transferred from piston 1 and 2

Solution :By applying Kirchhof's law charge transferred by TE batter is `80/19C`.
