The class is about Electricity and Magnetism. The website wants exactly the perfect answer and in the same metric system units that are stated on the calculators that are on the picture for the question, if not, it'll mark it wrong.

A at ring of inner radius R1 and outer radius R2 carries a total charge Q distributed unifotmly on its surface. Find the electric potential Von the 1: axis, a distance x from the center of the ring. Express your answer in terms of the given quantities and 50- -This is atypical problem requiring the use of (l) the potential of a point charge and (2} the superposition principle. Examples 23-8 and 23-9 tackle the very similar problems of the potential of a thin ring and of a at disk
