The positively charged plate of a parallel-plate capacitor has a charge equal to Q. When the space between the plates is evacuated of air, the electric field strength between the plates is 3.5 105 V/m. When the space is filled with a certain dielectric material, the field strength between the plates is reduced to 1.5 105 V/m.
(a) What is the dielectric constant of the material?
(b) If Q = 19 nC, what is the area of the plates?
cm2
(c) What is the total induced bound charge on either face of the dielectric material?
nC
