Homework Statement
Solid ball of charge with radius R and volume charge density ρ(r) = ρ0r2, centred at the origin.
I have already found the electric field for r<R and r>R and also the potential at the origin by using the formula:
V = -∫E.dl
Now i want to find the potential at the origin using the charge density but am at a loss for the first step
Homework Equations
V = (1/4∏ε)∫(ρ/r)d[itex]\tau[/itex]
The Attempt at a Solution
I don't need the full solution, just the first step would be much appreciated.
