A solid nonconducting sphere of radius R = 5.7 cm has a nonuniform charge distribution of volume charge density ρ = (14.4 pC/m3)r/R, where r is radial distance from the sphere's center. (a) What is the sphere's total charge? What is the magnitude E of the electric field at (b) r = 0, (c) r = R/2.0, and (d) r = R?
