Electrostatic FieldSchey's Notation

  1. Nov 16, 2009 #1
    Hey there,

    I am just seeking some clarification wrt the notation that I have come across for the Electrostatic Field:


    So are all of the 'primes' just saying that the [itex]\rho,\hat{u}, dV[/itex] are simply those that correspond to the same location?

    It seems like it is just a 'shorthand' notation to avoid a bunch of subscripts.

    Is this correct?

    All the "primes" are correspond to the source [tex]dq[/tex] of your (continuous) charge distribution, when [tex]\mathbf{r}[/tex] corresponds to the filed point, i.e. the point, where you want to find [tex]\mathbf{E}[/tex].
    [tex]|\mathbf{r}-\mathbf{r'}|[/tex] is simply the distance between the source [tex]dq[/tex] and the field point [tex]\mathbf{r}[/tex].
