Someone please tell me is I am doing this problem correctly.If I have a thick spherical shell with inner radius r, outer radius R, and mass M, I am getting [(2/5)M/(R^3-r^3)](R^5-r^5). It is not the same thing as subtracting I of large sphere from I of smaller one, different than (2M(R^2-r^2)?(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\frac{\2

(M(R^5-r^5))}{5(R^3-r^3)} [/tex]
