A slab of copper of thickness b = 1.250 mm is thrust into aparallel-plate capacitor of C = 9.00×10-11 F of gap d = 6.000 mm,as shown in the figure; it is centered exactly halfway between theplates. A charge q = 4.00×10-6 C is maintained on the plates.

a) What is the ratio of the stored energy before to that after theslab is inserted?

b) How much work is done on the slab as it is inserted?

Area is NOT given which is why I am confused on this problem.

A slab of copper of thickness b = 1.71 mm is thrust into a parallel-plate capacitor of plate area A = 3.24 cm2 and plate separation d = 4.05 mm, as shown in Fig. 25-57; the slab is exactly halfway between the plates. (a) What is the capacitance after the slab is introduced? (b) If a charge q = 2.91 µC is maintained on the plates, what is the ratio of the stored energy before to that after the slab is inserted? (c) How much work is done on the slab as it is inserted?

Two parallel plates, each having area A = 2797cm2 areconnected to the terminals of a battery of voltage Vb = 6 V asshown. The plates are separated by a distance d = 0.53cm. You mayassume (contrary to the drawing) that the separation between theplates is small compared to a linear dimension of the plate.
1) What is C, the capacitance of thisparallel plate capacitor?
What is Q, the charge stored on the top plate of thethis capacitor?.
A dielectric having dielectric constant ? = 4.5 is nowinserted in between the plates of the capacitor as shown. Thedielectric has area A = 2797 cm2 and thickness equal to half of theseparation (= 0.265 cm) . What is the charge on the top plate ofthis capacitor?
What is U, the energy stored in thiscapacitor?

The battery is now disconnected from the capacitor andthen the dielectric is withdrawn. What is V, the voltage across thecapacitor?
