Hi, I have a problem with finding charge distribution. If anyone could provide help or any tips as to how to solve it, I would greatly appreciate it.(adsbygoogle = window.adsbygoogle || []).push({});

I have already solved half of the problem.

The potential V(r) of a spherically symmetric charge distribution is given by V(r) = (Q/4*Pi*e0*R)[-2 + 3(r/R)^2] for r<R and V(r) = Q/4*Pi*e0*r for r>R. Use Gauss's law applied to Gaussian surfaces at various radii to calculate the charge distribution that gives rise to the potential given.

First I found the Electric field. -dV/ds=E

E(r<R) = (Q/4*Pi*e0)(6r/R^3)

E(r>R) = (Q/4*Pi*e0*r^2)

How would I find the charge distribution?

Thanks for any help! =)
