The diagram below shows the electric field lines in a plane containing the rod
The electric field at a point on the perpendicular bisector of a charged rod was calculated as the first example of a continuous charge distribution, resulting in Equation
a. Find an expression for the electric field when the rod is infinitely long.
b. An infinitely long rod with uniform linear charge density λ also contains an infinite amount of charge. Explain why this still produces an electric field near the rod that is finite.
