**2. Homework Equations**

q=cv

**3. The Attempt at a Solution**

C12=24nF

C34=36nF

C125=18nF

C12345=12nF

q5=q12=q34=(C34)(V34)

V24=5/36

V24=0.1389

lol i donno...can someone help me out. I dont understand this. I know q's are equal in series and V's are equal in parallel but then i get stuck. Please help

Thanks
