A solid non-conducting sphere of radius R = 5.60 cm has a non-uniform charge distribution of volume

Question:

A solid non-conducting sphere of radius R = 5.60 cm has a non-uniform charge distribution of volume charge density p: (14.1pC/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,

(d) r = R?

(e) Sketch a graph of E versus r.
