A solid non-conducting sphere of radius R = 1.12m.
The sphere posses a total charge Qtot spread uniformally throughout its volume.
a) derive equations for electric field for
result in terms of r R and Q
b) Derive an equation that gives the work needed for you to bring a point charge "q" from infinitely far away to inside the sphere at r = R/2
Answer is W = 11/8 (kQ/R) q
E1 = KQR/r^3
E2 = KQ/R^2
The Attempt at a Solution
q∫KQR/r^3 + q∫KQ/R^2
