Jan 23, 2019 at 19:20 comment added G. Smith Oh, of course. Sorry about that, FGSUZ.
Jan 23, 2019 at 19:18 comment added BioPhysicist @G.Smith I think FGSUZ is talking about the Coulomb's law equation
Jan 23, 2019 at 19:14 comment added G. Smith @FGSUZ The divergence of a vector is a scalar. There should be a vector sign over the $\nabla$ for clarity, but not a unit vector on the right hand side.

Jan 23, 2019 at 19:12 comment added FGSUZ 2 things. 1) Field and divergence of a field are not the same. 2) The electric field is not defined on the charge itself. You forget that vector = vector. Where is the vector in your RHS? You missed a unit vector $\hat{r}$. Where does it point to? It's undefined
Jan 23, 2019 at 19:11 comment added G. Smith Just calculate the divergence of the Coulomb field you wrote and you will see that it is zero everywhere except at $r=0$.
