Consider a uniformly charged spherical shell of radius R with a total charge Q. What is the electric field outside of the shell where r > R? No need to derive it. Just state what the field is in terms of the given and known quantities. Your answer to the previous question is completely general - it works for any point outside of the shell. Consider a point located very close to the surface of the shell. From that point, the sphere looks like an infinite plane of charge. One would expect the electric field predicted by the plane-of-charge model be consistent with that predicted by the spherical model. Is this true? If your answer is yes, present your work. If your answer is no, explain why not.
