Total energy stored in the electric fields, exess energy

[Vaidotas151]

Homework Statement

one capacitor is charged until its stored energy is 4.0 J, the charging battery then being removed. a second uncharged capacitor is then connected to it in parallel. if the charge distributes equally what is now the total energy stored in the electric fields? where the exess energy go? Answer must be 2 J
