A non conducting solid sphere of radius 8.40 centimeter has a uniform volume charge density. The magnitude of the electric field at 16.8 centimeter from the sphere's center is 2.21 x 103 N/C.
(a) Evaluate what is the sphere volume charge density?
(b) Determine the magnitude of the electric field at a distance of 5.00 cm from the sphere's center.
