A region in space contains a total positive charge Q that is distributed spherically such that the volume charge density rho (r) is given by:
rho (r)=3 * alpha * r /(2R) for r ≤ R / 2
rho (r)= alpha * [1-(r/R)^(2) ] for (R/2) ≤ r ≤ R
rho (r)=0 for r ≥ R
Here alpha is a positive constant having units of C/m^3What fraction of the total charge is contained within the region (R/2) ≤ r ≤ R?
If anyone can help me with this problem it would be greatly appreciated. I am getting lost in all the integration with everything. Thanks
