    Hi there,

    Looks a bit like homework, for which we have a nice template !

    Is it allowed to simplify this exercise to a sphere with the origin at the center ? Because if it is about a cube with the origin way outside of the cube, things seem complicated to me...

    In the simple case ##\vec r ## goes to ## \vec r'= {\rm \ ?} ## so that ## \vec h = \vec r'- \vec r = {\rm \ ?} ## and that you can subject to the divergence operation (from its definition) , I should hope ?

    Its okay, I have sorted out my queries. But thank you. I didn't know whether to post this in homework as it is not technically homework, as Im doing it a while in advance so I was hoping more for general background information than for specifics on how to do the question. :)

    Please don't delete the original post -- it makes the thread incomprehensible !

    Was your answer ##3\alpha## ?

    What kind of background info did you have in mind ?

    Kind of- I got the volume increase to be 1+divh, which is the same thing?

    Well, effectively you did by overwriting it. Perhaps you can restore the original ?

    Relative, I assume. Sounds good. Can you underpin it ?
