Question

What is Electric Field due to Infinitely Long Line of Charge?

Answer

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]
