Q30: Why is the following situation impossible? An automobile has a vertical radio antenna of length , l= m. The automobile travels on a curvy, horizontal road where the Earth’s magnetic field has a magnitude of B = mT and is directed toward the north and down- ward at an angle of u = below the horizontal. The motional emf developed between the top and bottom of the antenna varies with the speed and direction of the automobile’s travel and has a maximum value of mV. S app ?
