### Parallel-Plate Capacitor AnalysisA parallel-plate capacitor consists of two square plates with a side length of \(s = 2.30 \, \text{cm}\) and a plate separation of \(d = 3.00 \, \text{mm}\). The capacitor is initially charged by a battery to a charge \(Q = 4.50 \, \mu\text{C}\), after which the battery is disconnected. Subsequently, a porcelain dielectric \((\kappa = 6.5)\) is inserted into the capacitor to a distance \(y = 1.00 \, \text{cm}\) as illustrated in the figure below.#### Diagram DescriptionThe provided figure presents a parallel-plate capacitor:- The left plate is positively charged with \(+Q\) and the right plate is negatively charged with \(-Q\).- A dielectric material partially fills the space between the plates, occupying a distance \(y\) from the bottom.- The dimensions and positions are clearly marked: - \(s\) represents the side of the square plates. - \(d\) represents the separation distance between the plates. - \(y\) signifies the portion of the plate separation filled by the dielectric.#### Questions(a) **Determine the effective capacitance of this capacitor:** \[ \boxed{\text{pF}} \](b) **Calculate the energy stored in the capacitor:** \[ \boxed{\text{J}} \]
