capacitance, Physics

a 8 microfarad capacitor is charged to V=120V. the charging battery is then removed and the capacitor is connected in parallel to an uncharged 4 microfarad capapcitor. (a) what is potential diff across the combination. (b) what is stored energy before and after the switch S is thrown ?
