At a distance of 60.0km from a radio station antenna the electric-field amplitude is 7.90 x 10-2 V/m .
Part A
What is the magnetic-field amplitude at this same point?
Part B
Assuming that the antenna radiates equally in all directions (which is probably not the case), what is the total power output of the station?
Part C
At what distance from the antenna is the electric-field amplitude equal to half the value given?
