    Could you please help me with the query included in the attachment? Thank you for the help.


    PS: I think the relation shown in the attachment is correct because the following definition also says the same.

    electric flux density A measure of the strength of an electric field generated by a free electric charge, corresponding to the number of electric lines of force passing through a given area. It is equal to the electric field strength multiplied by the permittivity of the material through which the electric field extends. It is measured in coulombs per square meter. Also called electric displacement.

    UPDATE: Thanks a lot for giving it a look. But I believe I have found the answer. The following links helped me.


    Once again, thanks.
