Exam 24: Gausss Law

Charge is distributed uniformly throughout a large insulating cylinder of radius R.The charge per unit length in the cylindrical volume is λ. (a)Use Gauss's law to find the magnitude of the electric field at a distance r from the central axis of the cylinder for r < R.Your answer should be in terms of r,R,λ,ε₀ ,and π. (b)Check the reasonableness of your answer by evaluating it at the surface of the cylinder.
