An infinitely ong insulating cylinder of radius r1 has a charge uniformly spread throughout its volume so that the charge per unit volume is p. It is inside a conducting cylinder with inner radius r1 and outter radius r2. Find the difference in the electric potential between a point on the axis, at the center of the cylinder, and a point a distance 2r2 from the axis of the cylinder

High schoolphysics 5+3 pts a neon light consists of a glass tube with metal wires at each end. when connected to a high-voltage source, the gas glows. if a fly lands on the glass tube, what will most likely happen? a) the fly will not feel a shock because the glass conducts any free electrons back into the gas. b) electrons will flow directly from the metal wires along the glass and shock the fly. c) the fly will not feel a shock because the glass insulates it from the electrons in the gas and the metal. d) electrons that are moving through the gas will be conducted through the glass and shock the fly.
