    I saw only 4 problems in the document.The third one (with the charged sphere) is trivial.The formula reads (i'm a theorist,so i'll let u put in the numbers)
    [tex] Q=\frac{\rho}{8}\frac{4\pi}{3}(r_{1}^3 -r_{2}^3) [/tex].
    Pay attention with the units(centimeters for radius,Coulomb/cubic meter for the volume charge density). I hope u see where that "8" is coming from.If u don't,try to learn basical geometry before any phyiscs.
