Question

If a body or a surface is considered to have electric flux should it contain charge particularly in addition to the number of lines of force entering and leaving it?

Answer 1

the net flux that is zero for an uncharged gaussian body (or closed surface). Electric field lines of force begin from a positive charge and terminate in a negative charge. If the net charge of a body is zero then the net number of electric field lines emerging from it or terminating in it is zero...........hence it has a net electric flux equal to cipher (zero).
