Question

Electric field of an infinitely long conductor of charge density λ, is given by E = λ/(2πεh).aN. State True/False.

(a) True

(b) False

This question was posed to me in my homework.

The origin of the question is Electric Field Intensity topic in chapter Electrostatic Fields of Electromagnetic Theory

Answer 1

Right option is (a) True

To explain I would say: The electric field intensity of an infinitely long conductor is given by, E = λ/(4πεh).(sin α2 – sin α1)i + (cos α2 + cos α1)j

For an infinitely long conductor, α = 0. E = λ/(4πεh).(cos 0 + cos 0) = λ/(2πεh).aN.
