    According to Gauss' law, the electric flux through a closed surface is where is the charge enclosed within the closed surface and is the permittivity of free space.
    The field strength at a point in the field is the flux per unit area normal to the surface.
    The mathematical form of Gauss' law is given as

    "Electric flux E emerges from a positive charge and terminates on a negative charge or goes to infinity."
    ( is the angle between the field and outward normal to the surface) gives the total flux coming out of the closed surface. If we consider a closed surface such that either the field is normal to the ...
