8. [115 Points] DETAILS BAUERPHYSZ 24.P.060. MY NOTES A dielectric slab with thickness d and dielectric constant K = 2.91 is inserted in a parallel place capacitor that has been charged by a 110-V battery and having area A = 100 cm2, and separation distance d = 3.00 cm. (a) Find the capacitance, C, the potential difference, V, the electric eld, E, the total charge stored on the capacitor Q, and electric potential energy stored in the capacitor, U, before the dielectric material is inserted. (b) Find C, V, E, Q, and U when the dielectric slab has been inserted and the battery is still connected. (c) Find C, V, E, Q, and U when the dielectric slab is in place and the battery is disconnected. (Assume the battery is first disconnected, and then the dielectric slab is inserted.) '1.
