Charging of Capacitor

The charge on capacitor is

A capacitor of capacity C is charged to a potential difference V and another capacitor of capacity 2C is charged to a potential difference 4V . The charged batteries are disconnected and the two capacitors are connected with reverse polarity (i.e. positive plate of first capacitor is connected to negative plate of second capacitor). The heat produced during the redistribution of charge between the capacitors will be

An air capacitor is charged upto a potential V_1 . It is connected in parallel to an identical uncharged capacitor filled with a dielectric medium. After redistribution of charge if the potential difference of this combination is V, then the dielectric constant of the substance will be
