Solve the all parts of given problem:
Problem: An infinitely long cylindrical non-conductor is uniformly charged with a volume density of 6 C/m3. The cylinder has a radius of 8 cm.
Part A: Calculate the electric field at a distance of 1 m from the axis of the cylinder.
Part B: What happens if the distance from the axis is less than the radius? Calculate the electric field at a point 3.6 cm from the axis of the above infinite cylinder.
Show how you get the answer, so that I can better understand how to do it.
