A 5.0 microfarad parallel plate capacitor has a charge of +49.0 microfarad and -55.0 microfarad on each plate, respectively. What is the potential energy stored in this capacitor?

    @Arzola99 did you mean 55 microvolts instead of 55 microfarad?

    You need to use the c = q/v relation to find v. Then use the capacitor potential energy equation

    Do I use that equation for each charge and add them?

    I believe the q in the equation refers to the total charge so yes you would add them
