## Homework Statement

Please calculate the potential for a sphere that is uniformly charged with density ρ

_{0}and also has a radius of R.

a. r<R

b. r>R

c. Is there a discontinuity of Electric Field at the surface? Explain your reasoning.

## Homework Equations

## The Attempt at a Solution

I have attached my work for the first two parts, which I am pretty sure is correct. However, I need help with the last part. I want to say that it is continuous, because of the nature of uniformly charged spheres. However I don't know if this is right, or how to really explain it. This is due tomorrow, so any help (especially if it's quick) would be GREATLY appreciated. Thank you.
