Consider a thin infinitely long straight charged wire of linear charge density λ.
Let P be the point at a distance ‘a’ from the line. To find electric field at point P, draw a cylindrical surface of radius ‘a’ and length l.
If E is the magnitude of electric field at point P, then electric flux through the Gaussian surface is given by,
<dl> <dd>Φ = E × Area of the curved surface of a cylinder of radius r and length l
Because electric lines of force are parallel to end faces (circular caps) of the cylinder, there is no component of field along the normal to the end faces.
Φ = E × 2πal … (i)
According to Gauss theorem, we have
From equations (i) and (ii), we obtain
