Question

 

A thin rod of length has a uniform charge . Derive an expression for the electric field at point P on the axis of the rod that is at a distance from the center of the rod. Show that in the limit as , the electric field due to the rod is the same as if the rod is a charged particle.


Figure: Efield on the axis of a uniformly charged thin rod.
