What is the charge on the 32 μF centered-
upper capacitor?
Answer in units of μC


Homework Equations


Q = CV
1/c = 1/c1 + 1/c2......



The Attempt at a Solution


I found the charge across the entire thing and then divided that by 2, since the charge should be the same on all the plates. But that was wrong.
