Divergence of the Electric Field

  1. Mar 6, 2015 #1
    I am having a problem with this concept, when looking at the fields from a point source.


    My problem is that the field gets weaker the further it gets from the source, so at any point away from the source should there not be more entering that point than leaving it, and so have a negative divergence.

    (a) ⇐⊕⇒ (b) ⊕⇒→
    (a) is a source and looking at the divergence of the field here would give you a positive term.
    (b) is the part that confuses me, should the point between the big and small arrows not have a negative divergence, as there is more of the vector quantity entering than leaving.

    Any help would be great Thanks.
