A fully loaded aircraft has a mass of 3 × 105 kg. The total wing area is 300 m2. If it is in level flight with a speed of 900 km/hr, then find the difference between the speed of the air on the upper surface of the wing relative to the lower surface. (Take density of air ρ = 1 kg/m3 and g = 10 m/sec2)
1
20 m/sec
2
40 m/sec
3
10 m/sec
4
None of these
