The visible portion of a lightning is preceded by an invisible stage in which a column of electrons moves from a cloud to the ground. The linear charge density λ along the column is typically -1 x 10-3 C/m. If air molecules are ionized in an electric field exceeding 3 x 106 N/C, what is the radius of the column?
