Question: How to solve differential equation for potential

Dear Maple Users

I wonder how I can use Maple to solve the problem:

 

for the potential \phi(r). The problem is from the artikle: http://en.wikipedia.org/wiki/Electric-field_screening

I'm particularly puzzled how to implement this differential operator and how to enter the Dirac delta function.

 

Thanks for any hints.
