A radio station on the earth's surface emits a sinusoidal wave with average total power 50 kW. Assuming that the transmitter radiates equally in all directions above the ground (which is unlikely in real situations), find the electric-field and magnetic- field amplitudes Emax and Bmax detected by a satellite 100 km from the antenna.
