Problem
A straight wire that starts at x=0 and extends to +∞ carries a uniform linear charge density λ. A point charge q is located on the wire’s axis at a distance d from the nearer end of the wire. Derive an expression for the magnitude of the electrostatic force acting on the point charge in terms of λ, d, and fundamental constants.
