An aeroplane with wing area 100 m2 is travelling in a level flight at a speed of 800 km/h. Using sensors placed on the surface, above and below the plane, it has been deduced that the speed of air above is 10% higher than that of the below. Assuming density of air to be 1.5 kg/m3, the mass of the plane is
