Physics: What charge distribution does this potential represent?

Question

Any help is appreciated on this. I don't really understand it.

Given: V = kq/(x^2 + y^2 + z^2)^1/2
I Found: E = [kq(x + y + z)]/(x^2 + y^2 + z^2)^(3/2) Question:

What charge distribution does the potential represent? (It doesn't ask why, but if you could explain I would be greatful, Thanks!)

Answer 1

Now that you have the E field, you need to solve for Q. Use the correct Maxwell's equation to solve for the charge distribution. (A charge creates an electric field.)
That should put you back on the right track.
The charge distribution would just be the mathematical representation of how the charge is distributed throughout the space. So Q would be a function of x, y, and z.
