Homework Equations

Q = CV
E = Q²/(2C)
E = 1/2*C*V²


I thought since they were parallel the voltage across each was the same so E = 1/2*36*10⁶*30² but that gives me .0162 and that's not an option, .0016 is

They are not all in parallel. Hint: Redraw the circuit to identify the parallel/series combinations.
