A metal airplane having a wingspan of 30m flies horizontally all along a north-south route in the northern hemisphere at a constant speed of 320 km/h in an area where the vertical component of the magnetic field of earth is 5.0 x10 to the negative fifth T.
(i) Determine the magnitude of the induced emf among the tips of the wings?
(ii) When the easternmost wing tip is negatively charged, is the plane flying due north or south? Describe.
