A satellite orbits Earth with an orbit radius equal to 4 × 107 m (measured
from the center of the Earth). The satellite transmits electromagnetic waves to
2 × 109 Hz. Assume that the satellite transmits the radiation evenly
in all directions. The intensity of the EM wave received by an antenna
circular on the Earth's surface is 2 × 10-12 W / m2 when the satellite is
located 3 × 107 m above the antenna. The antenna disk has a radius of 2m.
A. Determine the wave of radiation from the satellite. 

b. Calculate the total power of the satellite. 

c. Calculate the amplitude of the electric and magnetic field at the surface
of the antenna. [Express your answer using symbols] 

d. Suppose that the radiation from the satellite strikes the
antenna. If the radiation is completely absorbed by the antenna,
Calculate the force that the radiation exerts on the antenna.
