So sorry I didn't mind it....the formula....is..E=lambda/(2 pi epsilon not × r) and E=q/(2 pi epsilon not × r × l)...

Gauss law is used for closed surface that should be mentioned properly...

Khushi....? ??‍? 5 years, 3 months ago

Gauss's Law is a general law applying to any closed surface. It is an important tool since it permits the assessment of the amount of enclosed charge by mapping the field on a surface outside the charge distribution. For geometries of sufficient symmetry, it simplifies the calculation of the electric field.
