[Urgent] Please help me out to solve this problem. You actually can skip explanations, but equations, units and answer are required.

2. Consider the circuit with 4 capacitors (C1, C2, C3, 85 C4) a battery (V5) and two switches (81 & SQ). (a) (10 points) Determine the equivalent capacitance of the circuit where C1 = C, Cg = $0, C3=C4=C with all switches closed. (b) (C) (5 points) Choose a numeric value for the capac- itance C with the appropriate units. What would be the numerical value and unit of the equivalent capacitance? (10 points) All the capacitors are initially un- charged. You replace the capacitors 01 and 02 with two resistors. You close both switches and go get a glass of milk. When you return, what is the current across resistor R1 and the current across resistor R2
