Why Does the Laplacian of 1/Vector r Equal Zero?

[QUOTE="TSny, post: 4959007, member: 229090"] You're right, it does look like ##1/\vec{r}##. I think it must be a misprint. It does turn out that ##\nabla^2(1/r)=0## (except at ##r = 0##). So, I'm thinking that's what was meant. [SIZE=3]Part (c) also seems to have some misprints, unless the author is purposely trying to test whether you can tell if an expression is meaningless.[/SIZE] [/QUOTE]
