A) \[\frac{\lambda }{4\pi {{\varepsilon }_{0}}d}\]
B) \[\frac{\lambda }{2\pi {{\varepsilon }_{0}}d}\]
C) \[\frac{\lambda }{\pi {{\varepsilon }_{0}}d}\]
D) Can't be found
Correct Answer: D
Solution :
In this case, we can't take reference point for potential at infinity as wire itself is of infinite dimension and hence we can't define absolute potential due to infinite (charged) wire. Only potential difference between two points can be found, provided none of the point lies on wire.
