일반물리학 2 — Electric Potential: Problem 45
45 A metal sphere of radius 30 cm has a net charge of \(3.0 \times 10^{-8}\text{ C}\). (a) What is the electric field at the sphere’s surface? (b) If \(V = 0\) at infinity, what is the electric potential at the sphere’s surface? (c) At what distance from the sphere’s surface has the electric potential decreased by 500 V?
