Electric Field due to Infinitely Long Line of Charge…

Electric Field due to Infinitely Long Line of Charge – For a uniformly charged wire of an infinite length having a constant linear charge density,
i.e. (λ = Charge/Length), electric field at point P at a distance r is given by
∫E ds = Q/ε0
⇒ E = λ/2πε0r = 2kλ/r [Where, k = 1/4πε0]
