Field near a stick **

A stick with length 2R has uniform linear charge density λ. Con- sider a point P, a distance ηR from the center (where 0 ≤ η 1), and an infinitesimal distance away from the stick. Up close, the stick looks infinitely long, as far as the E component perpendicu- lar to the stick is concerned. So we have E⊥ = λ/2π E0r. Find the E component parallel to the stick, E . Does it approach infinity, or does it remain finite at the end of the stick?
