Hi, I've attached a diagram of the question. The real question reads differently, but I've done my own interpretation. The interpretation might be wrong/ right, but its left me thinking anyway. So, I'd appreciate any advice/ hints on how I might go about finding the capacitance. I have tried it. I reasoned that the voltage across both segments are the same, due to the 'parallel' configuration, and then attempted to solve one of the pairs' capacitance by taking note of the fact that the charge surface density on one is half the other. Then I multiplied the result by 2, according to parallel capacitor combinations. I got the wrong answer though. Its kinda urgent, cause my exam's coming soon. I'd appreciate any advice at all. Small or big. Thanks a lot.
