Suppose a radio station emits EM waves uniformly in all directions. What is the maximum power level of this radio station so as to avoid electrical breakdown of air at a distance of 2.0m from the antenna? Assume the antenna is a point source. Air breaks down in an electric field of about 3*10^6V/m.
