1. Do we consider bound charge densities in applying the boundary con- ditions?
2. When we apply Gauss's law in a dielectric medium, should we take into account the bound charge densities?
3. An electric field is given by -E = 10-a x + 20a-y + 20a-z V/m. Is this a uniform field? Why? What is its magnitude? What are the cosines of the angles it makes with the unit vectors?
