An emitting antenna radiates an electric field which rms value is 5 V/m at a distance of 8 m. We suppose that the antenna radiates an electromagnetic wave isotropically through a spherical surface. What is this rms value at a distance of 6 m?
The answer will be given with three significant figures and with its unit.
