Please help with this question

(20 pts) Two capacitors C1 = 3.1 /F and C2 = 2.3 MF capacitor are connected in series. A charge of 6.20 mC is placed on each capacitor. CZ (a) (5 points) What is the total energy stored in the capacitors? (b) (5 points) A resistor R1 = 500 $ is connected to the terminals of the capacitor combination, as shown in the figure. What is the rate of change of energy stored in the capacitors just after the connection is made? (Hint: Think about what circuit element is dissipating energy in the circuit)(c) (10 points) How long after the connection is made has the ENERGY stored in the capacitors decreased to half of its initial value
