Two capacitors of equal capacitance ( C1 = C2 ) are as shown in the figure. Initially, while the swithc is open (as shown) one of the capacitors is uncharged and the other carries charge Q0. The energy stored in the charged capacitor is U0. Sometime after the switch is closed, the capacitors C1 and C2 carry charged Q1 and Q2 respectively, the energy stored in the capacitors are U1 and U2 respectively. Which of the following expression is correct?
