Flux through Gaussian sphere

  1. Feb 13, 2013 #1
    1. The problem statement, all variables and given/known data
    An insulating sphere of radius R has positive charge uniformly distributed throughout its volume. The volume charge density (i.e., the charge per volume) is ρ.

    What is the flux through a Gaussian spherical shell of radius R/2 that is totally contained inside the charged sphere and centered a distance R/2 from the center of the charged sphere, as shown by the dashed sphere in the diagram below?

    2. Relevant equations

    3. The attempt at a solution
    I initially took ρ times the volume enclosed (4/3)*∏*(r/2)^3 and then divided that by Eo. But it didn't give me the correct result
