An am radio station broadcasts with an average power of 6.02 kw. a dipole receiving antenna 98.3 cm long is located 3.46 km from the transmitter. assume the transmitter is a point source, the waves are traveling perpendicular to the axis of the receiving antenna, and that the source is far enough away that the wave amplitude is constant along the receiving antenna. compute the amplitude of the induced emf by this signal between the ends of the receiving antenna. µo c = 377 ω and 1.609 km = 1 mi. answer in units of v.
