Air is blowing across the horizontal wings of an aeroplane in such a way that its speeds below and above the wings are 80 m/s and 120 m/s respectively. If the density of air is 1.2 kg/m^3 then the pressure difference between the lower and the upper sides of the wings will be

An aeroplane having a distance of 50 metre between the edges of its wings is flying horizontally with a speed of 360km // hour. If the vertical component of earth’s magnetic field is 4 xx 10^(–4)" weber"//m^(2) , then the induced emf between the edges of its wings will be –
