A nonconducting solid sphere of radius 11.2 cm has a uniform volume charge density. The magnitude of the electric field at 22.4 cm from the sphere's center is 2.13 *10^3 N/C.
(a) What is the sphere's volume charge density?
µC/m3
(b) Find the magnitude of the electric field at a distance of 5.00 cm from the sphere's center.
N/C
