Solve the given parts of following question:
Question: The electric field everywhere on the surface of a charged sphere of radius 0.280 m has a magnitude of 570 N/C and points radially outward from the center of the sphere.
Part A: What is the net charge on the sphere?
Part B: What can you conclude about the nature and distribution of charge inside the sphere?
I don't just need an answer, work and explanations/walkthrough would be much appreciated! Thanks.
