?
k = 1/permittivity
This is not true.
k is defined in terms of the vacuum permittivity. You
do not use a different value of k in different media.
Remaining material deleted as it proceeds from this
false assumption.

Well, if I asked you to calculate the electric field inside a
dielectric, would you ignore the dielectric constant?
