Question: A non conducting solid sphere of radius 8.40 cm has a uniform volume charge density. The magnitude of the electric field at 16.8 cm from the sphere's center is 2.21 x 103 N/C.
Part A: What is the sphere's volume charge density?
Part B: Find the magnitude of the electric field at a distance of 5.00 cm from the sphere's center.
Please show all steps to find the sphere's volume charge density.
