 P: 2 1. The problem statement, all variables and given/known data A uniform charge q is distributed along a sphere of radius R. a) What is the Electric Potential in the center of the sphere? 2. Relevant equations V(r1)-V(r0) = - $$\int \stackrel{\rightarrow}{E}$$ * $$\stackrel{\rightarrow}{dl}$$ 3. The attempt at a solution
 P: 2 Thanks for answering, but actually I can't find the expression for the second part of the Electric field The first is inside the sphere wich leads to $$\frac{Kq}{R}$$ but the Electric field of the outside part of the sphere I don't know what to do obs: the answer is : $$\frac{6kq}{R}$$
