Hey guys.

So, I got this question in the pic.

First of all, I drew what I think to be a one-dimensional lattice (in the green box) but I'm not sure, is it right?

Second of all, I don't really understand the question, I mean I know that a potential energy of charge q is V(r) = kq/r when you say of curse that v(infinity) = 0 but what do they mean by a "potential energy of a single charge"?

Thanks in advance.
