Gauss law application part 1, Infinite line of charge class 12th, Electrostatic by Amit dwivedi

The electric field of an infinite line charge with a uniform linear charge density can be obtained by a using Gauss' law. Considering a Gaussian surface in the form of a cylinder at radius r, the electric field has the same magnitude at every point of the cylinder and is directed outward.
