4. A 75.0-kW source emits electromagnetic waves uniformly in every direction. At a point located 200 m from the source, find (a) the rate at which energy is delivered through a 0.250-m² surface, and (b) the amplitudes of the electric and magnetic fields. (c) If the amplitude of the electric field is 3.00 × 106 V/m, air will experience electrical breakdown. Find the maximum power of the source that avoids breakdown 1.50 m from the source.
