Q31. An oscillating current I)=1, exp(-iot) flows in the direction of the y-axis through a thin metal sheet of area 1.0 cm kept in the ay-plane. The rate of total energy radiated per unit area from the surfaces of the metal sheet at a distance of 100 m is (a) l/127e,) () /(12) b) o12ne,e') (d) o'/(12me,e*)
