Homework Help: Electric field due to non uniformly charged spherical shell

  1. Jun 2, 2012 #1
    The volume charge density of spherical shell varies as ρ=-kr.If we have to calculate electric filed using gauss's law, can we treat as E. dA as E(dA) as there is azimuthal symmitry

    2. Relevant equations

    3. The attempt at a solution

    You want to integrate over the volume of the sphere to find the total charge enclosed. Then from there it's simple to find the electric field using Gauss's law.
