The average induced EMF (Electromotive Force) in the wings of a plane can be calculated using the formula: EMF = Bvl, where B is the magnetic field strength, v is the velocity of the plane, and l is the length of the wings. First, we need to convert the speed from km/hr to m/s: 500 km/hr = (500 * 1000 m) / (3600 s) = 138.89 m/s. Given B = 10^-5 T and l = 25 m, the EMF = 10^-5 T * 138.89 m/s * 25 m = 0.0347225 V. Since this value is not listed among the options, the correct answer is E) none of the above.
