An infinitely long uniform line charge distribution of charge per unit length lies parallel to the y-axis in the y-z plane at a (see figure). If the magnitude of the flux of the electric field through the rectangular surface ABCD lying in the x-y plane with its centre at the origin is ( = permittivity of free space), then the value of n is
