A charged paint is spread in a very thin uniform layer over the surface of a plastic sphere of diameter 13.0 cm , giving it a charge of -39.0 μC
a-Find the electric field just inside the paint layer.
b-Find the electric field just outside the paint layer.
c-Find the electric field 7.00 cm outside the surface of the paint layer.
Again negative sign shows that direction of E is opposite to the direction shown in figure i.e. E is directed towards the center of sphere.
