Here is the question which I am struggling on, please help me!
Question: A Boeing KC-135A airplane has a wingspan of 39.9 m and flies at constant altitude in a northerly direction with a speed of 850km/h.
If the vertical component of the Earth's magnetic field is 5.0×106 T, and its horizontal component is 1.4×106 T, what is the induced emf between the wing tips?
I need help for the above question.
