An open-ended (hollow) cylinder of radius R = 1.1 m and length = 9.4 m carries charge 5.5 nC that spreads uniformly over its surface. What is the potential (in unit of V) at the center of the cylinder? (Hint: treat the cylinder as a stack of charged rings, and integrate. Potential at infinity is zero.) Useful formula: dx := In (Vx2 + a² + x) + const x² + a²
