You are experimenting in a laboratory to study the behavior of a parallel-plate capacitor. The capacitor has a plate area of 1.5m² and a plate separation of 2.0mm. It is connected to a 50-V battery, which charges it. Your objective is to determine the charge accumulated on the capacitor, the strength of the electric field between the plates, the capacitance of the system, and the energy U₀ stored in the capacitor.
