I have a sphere of uniform charge density and I need to find the potential inside and outside. I found it for the outside, but I am wondering if my solution for the inside is correct. I used dV = E*dl,(* being the dot product) For my lower limit I used r, where r < a and "a" being the radius. For the upper limit I used zero because when r is zero, I figured zero potential because you have zero charge. The only problem I get a negative potential? Does this sound right?(adsbygoogle = window.adsbygoogle || []).push({});

Thank You

Philip
