# Find the electric potential V(r)

Hi, I have a homework of electromagnetism and I got stucked in a problem, can you help me, please?

1. Homework Statement

Find the electric potential V(r) in the space produced by a density charge

(rho) = (rho)0 e-(alpha) r

In spanish:
Enuentra el potencial V(r), en todo el espacio, producido por una densidad de carga:
(rho) = (rho)0 e-(alpha) r

## The Attempt at a Solution

I know that the electric potential produced by a density charge is the volume integral of the density charge by the magnitud of the distance between but I don't know how to take distance in all the space[/B]
