The tube of a Geiger counter consists of a thin, straight wire surrounded by a coaxial conducting shell. The diameter of the wire is 0.0025 cm, and that of the shell is 2.5 c,. The length of the tube is 10 cm; however, in your calculation, use the formula for the electric field of an infinitely long line of charge. If the potential difference between the wire and the shell is 1.0x10^3 volts, what is the electric field at the surface of the wire? At the cylinder?
