5. a simple geiger counter is constructed out of a setup similar to what we just used in problem 4. a thin wire with a linear charge density ? is held in the center of a cylindrical tube, which is filled with an inert gas. when a high speed particle coming from a radioactive decay, cosmic ray, etc. enters the gas-filled tube, collisions with the gas knock electrons off of their atoms. the free electrons then accelerate towards the positively charged wire, and collide with other gas atoms causing them to lose electrons as well. this leads to a cascade of electrons accelerating towards the wire, which will be turned into a measurable current upon reaching the wire. for this problem, the tube
