In an aeroplane, the distance between the edges of its wings being 30m. During landing down its velocity is 300 Km/hr and wings of the aeroplane be east-west. Find out the potential difference between the edges of the wings. What happens if wings be north-south then?
[Hint : (In first case wings will cut BH and in second case neither BH or BV) (Give BH = 0.4 gauss and angle of dip at the place 60°)]
