    1. The problem statement, all variables and given/known data

    if a vecor A is both solenoidal and conservative; is it correct that


    that is

    A=- gradΦ

    Φ is a scalar function

    If A is just a conservative vector field, then [itex]A= -\nabla \phi[/itex] for some scalar function [itex]\phi[/itex]. I'm not sure what requiring that it also be solenoidal adds.

    well i thouhgt if A is only conservative

    [itex]A= \nabla \phi[/itex] (according to my text book)


    [itex]A= -\nabla \phi[/itex]

    so what is right?:confused:
