Compute all parts of given question:
Question: A charged paint is spread in a very thin uniform layer over the surface of a plastic sphere of diameter 15.0 cm, giving it a charge of -16.6 µC.
Part A: Find the magnitude of the electric field just inside the paint layer.
Answer in: N/C
Part B: Find the magnitude of the electric field just outside the paint layer.
Part C: Find the magnitude of the electric field 5.00 cm outside the surface of the paint layer.
