An 800-kHz sinusoidal radio signal is detected at a point 6.6 km from the transmitter tower

The electric field amplitude of the signal at that point is 0.780 V/m. Assume that the signal power is radiated uniformly in all directions and that radio waves incident upon the ground are completely absorbed. What is the amplitude of the magnetic field of the signal at that point? (?0 = 8.85 × 10-12 C2/N ? m2, c = 3.0 × 108 m/s, ?0 = 4? × 10-7 T ? m/A) A) 1.6 nT B) 3.1 nT C) 3.6 nT D) 2.1 nT E) 2.6 nT
