🧠 Gauss's Law Doesn't Care That It's a Capacitor

Read this question slowly. They are asking for electric flux through a closed surface that surrounds the positive plate. The word "capacitor" is there to scare you. Forget it. The moment you see "flux through a closed surface enclosing some charge", you should think of one thing only — Gauss's law: .

So the only job left is to find the charge on the positive plate. The capacitor has capacitance  and is charged to potential . The charge on the p
