Graph Chere: Graph D here: 5. What relationship exists between the capacitance C and the plate area A (Graph C)? 6. What is of the slope of the graph of C vs. A? What is the physical significance of the slope? 7. Show how the permittivity of free space is calculated using the slope of Graph C. 8. What relationship exists between the energy U stored on capacitor and area A (Graph D)? 9. There is vacuum (no matter) between the plates of a parallel-plate capacitor. The distance between plates is 28.0 mm and the area of each plate is 46.0 cm2. (1 mm = 10-3m and 1 cm2 = 10-4 m?). If the capacitor is charged through a 220 V supply, calculate the following (3 significant figures each): capacitance (in F) of the capacitor p) charge (in C) stored in the capacitor, and c) electric field (in N/C or V/m) between the plates.
