A certain sample of pure quartz has a dielectric constant of 3.8, dielectric strength of 1.0 kV/0.00010 in, and a density of 2.6 Mg/m3.
a.)A field of 5.0 kV/cm is applied. Determine the polarization.
b.) Assume the number density of dipoles in quartz is the same as the number density of SiO2 units. What magnitude of dipole strength has to be associated with these units under to support the polarization found under a field of 5.0 kV/cm?
