The distance between the two end-points of the wings of an aeroplane is 5 m and the aeroplane is flying parallel to earth's surface with a velocity of 360 km h^(-1) . If the geomagnetic intensity is 4xx10^(-4)Wb . m^(-2) and the angle of dip at that place is 30^(@) , determine the emf induced between the two end-points of the wings.

An aeroplane is travelling at the speed of 360 km//hr along the horizontal to the earth surface'. What is the induced potential developed between the ends of th'e wing 5 m long, if the earth’s magnetic field at the location has-a magnitude of 4 xx 10^-4 wb//m^2 and dip angle is 30^@ ?
