A capacitor has parallel plates of area 12cm^2separated by 2.5 mm. The space between the plates is filled with polystyrene (K=2.6,Em=2.0*10^7 V/m).
A) Find the permittivity of polystyrene.
B) Find the maximum permissible voltage across the capacitor to avoid dielectric breakdown.
C) When the voltage equals the value found in part B, find the surface charge density on each plate.
D) Find the induced surface-charge density on the surface of the dielectric.
